Thanks folks. Some good ideas, but it looks like Rodinal is getting the most votes. I also like the ideas that it's one-shot and will stand being warm in a half full bottle.
Thanks a lot to Eric Rose. We'll be in Calgary for a couple of days, staying with my wife's brother, and I'll give you a call. By that time, I'll probably be sick of bathrooms.
I'm thinking to take a separate box, like maybe a cheap plastic toolbox, and put in a bottle of something like Rodinal, concentrated liquid fix, wash aid, stop bath, photo-flo, the tank and reels, thermometer and a few plastic bottles to hold working solutions while they're being used. Everything will be in factory labelled bottles. If it's a night to develop, I'll just grab the whole thing and haul it into the room and go to work. The next morning, the dried negs can be cut and stored in sheets.
Is this kind of what you did Patrick R James?
Don't do this, at least if he used something labeled, anyone who would be suspicious would be able to google the name listed on the bottle and he wouldn't be arrested, if you are just carrying a bunch of empty non-branded bottles, you're sure to be suspicious and most likely have everything confiscated.. Lol
Another vote for Rodinal!

The only chemicals you need are developer, TF-4 fix and Edwal LFN. Skip the stop bath and wash aid (if you use TF-4). Keep life simple.
Both are excellent Stone and share many qualities. Some say TF-4 lasts better, some believe that being a bit acidic it works better with certain developers. I like TF-5 better because I believe there s less smell and find no fault with longevity or action in my work.
I wouldn't want to travel with TF-4 because it seems to have been designed to be completely mixed (as opposed to being a concentrate you can dilute as needed), although I suppose you could mix it into batches of stock and travel with those. Seems like a pain to me. TF-4 is an alkaline fixer by the way. TF-5 is a totally different formula and is close to neutral in pH.
Even if you use a standard acidic fixer you can skip washaid/hypo clearing anyway with film since the wash time is not all that long to begin with. One less chemical to travel with.
