I had this same thought, and my idea was to basically borrow from the earth-based travel industry..... Presumably the commonality between the systems will be the mixture being breathed (I think they long since did away with pure oxygen?). So the life support connections will likely have an air inlet and outlet. Next, Suits will no doubt need power no matter which ship you're on (heating/cooling, small lights). So there will be some sort of power jack included next to the air exchange ports. The unknown for me is whether there will be waste disposal plumbing... Or if it'll be like Scott said, with a suit hatch that handles that. So if anyone happens to be utilizing a plumbing system with no external hatch (which I think you'd still want, as a backup), that kills my idea... Which my idea is... Why not just make adapters? lol We have "Travel Adapters" for power, after all! Doesn't seem far fetched to have a similar adapter for life support. The biggest issue here being power delivery, as some providers may not have a suit power bus that's intended to supply high current, whereas another provider's suit might need it. So even if the voltage has to be bucked or boosted, if the total supplied wattage by the bus is insufficient, that would also nix this... But yea, a small adapter box that routes air from their connection style, to yours, and also provides whatever power conversion from their bus to your suit's needs. 👍 (of course, it'd be in everyone's best interest to standardize a port for this, regardless of which suit you're in, as needing to pack these various complex and heavy adapters for 2 different life support systems is a complete waste of mass budget...)

@asd1070 Robin Williams did a great bit on that in Robin Williams - Live on Broadway (which someone uploaded in its entirety some years back, whether it's still around though...)

@petermichaelgreen After a sleep, I think whatever it was I had recalled last night about suits using mixed, might've been backwards... I'll have to try and see what I can find on Google. Because now I have a strange feeling there was something mentioned about concern about potential "The Bends" situations... That ring any bells for anyone? 🤔 "The Bends" being an issue for scuba drivers where,, IIRC, nitrogen bubbles build up in the joints due to huge change in environmental pressure when diving deep; surfacing too quickly [aka decompressing too quick] can result in serious injury/death. If quick surfacing is needed [emergency] then moving directly into a pressurized vessel [a "decompression chamber"], which then slowly decompresses, prevents that. That's where my uncertainty in space is, and thinking you might be right about suits still being 100% O2....And more details are coming back to me as I type! (but still could be reversed from reality... lol) I believe that NASA uses pure, but SpaceX has opted not to, as doing so means.... <memory becomes hazy> Time to Google! 😊

@petermichaelgreen PART 2... So after ~30 minutes of fruitless effort in trying to track down details on what SpaceX plans to use for their EVA-capable spacesuit's air composition, OR FOR THAT MATTER, the article I'd read that would've discussed that.... I'm left do assume it's going to be, for now, the same as Crew Dragon's life support: 23% Oxygen / 77% Nitrogen. That being said... - We're correct on the abandonment of pure O2 use inside of ships and stations. - You're correct that NASA's suits ARE still 100% O2. - As such, before an EVA, an astronaut must first hand out in the airlock breathing the 100% O2 in order to purge the nitrogen from their bodies, to prevent "The Bends". (but I don't know if the airlock is filled and they breathe it as they suit-up, or if they have to wait an additional ~hour in the closed-but-unpressurized suit before they can pressurize it...) My thoughts are that where I'd originally read this was probably the ArsTechnica article about the upcoming SpaceX EVA by Issacman (?), which will be an umbilical suit tethered to Crew Dragon 2. I reread that article and there was no mention of what I'm recalling; however, I frequently read the comments for further insights, so it's probably_there_ that someone no doubt brought up the fact that CD2 lacks an airlock, and that it'll be interesting to find out if ALL the occupants will undergo the pure-O2 breathing, or if the EVA will be executed using the standard air composition... 🤷‍♂️ This concludes my lesson in: If I'm unsure... _then SHAAADDAAAAPPP!!_🥴😊
