emacs tramp and the remote environment

[Rodrigo Amestica]

I use tramp every day from home (it is a so great tool!) to compile
and run applications in a remote set of machines. At this moment the
only thing I'm missing is a better way for moving around the remote
file system. I mean, in the remote environment I set a few variables
that when running emacs locally would quickly let me go to directories
I need to visit, that is, C-x C-f $MYVAR tab

But with tramp on a remote machine all variable keep their local value
and, therefore, I cannot use them to browse the remote file system.

I thought that hooking a function that would somehow replace process-
environment with the remote one would do the trick. Then I saw in
tramp that there is already a variable named tramp-remote-process-
environment, but it seems to be meant to some other purposes.

Would it be there and advice on how to accomplish what I'm looking
for?

thanks,
 Rodrigo
