Well, I don't know what work is currently going on, but the key word
here is "eventually". Unless something has changed, the US ECLSS
equipment is all planned for the Hab module (or Node 3, or whatever it
is called this week). Which isn't even on the assembly sequence (I
was looking at http://spaceflight.nasa.gov/shuttle/future/index.html ).

I won't say it is impossible to do work now to improve equipment which
won't be used for 5-10 years, but I will say that having someone who
is using (or soon will use) the stuff you are building tends to
improve the quality of the engineering. At least, that's been true on
projects I've worked on.

I've been waiting for someone "in the know" to tell us the state of future
US ECLSS. I knew it was bad. I keep hoping that the US will find a way to
get ECLSS up earlier than the "HAB", but it doesn't look promising.
