Just saying I hadn't found them so far. And though I did use the word "plumbing" earlier in the thread, "pipe" !always=
"bus". Buses are for easy connection in any module, potentially at multiple points in a pallet or module. Propulsion &
RCS doesn't meet that criterion.

Since most of the attitude control is supposed to be done with gyros, with periodic nulling if needed using onboard RCS,
and since orbital adjustments are generally to be provided by Shuttle (talk about your "different unit"), *I* _could_
see the astronauts doing ISS propellant resupply on something like an annual basis "with 5 gallon gas cans". I'll let
you know when I find out.

I also haven't found an air bus yet (no puns, please). But I posit that such might exist.
