We do something similar, although split our software up into
"OS/distro/ISA" (i.e. Linux/RHEL4/i686) just to keep maximum
flexibility. That path suffix is configured in the $ARCHPATH variable
so that it's not really any extra overhead to any of the tools.
One of the really cool things about Modules is the power of Tcl - it's
allowed us to make our basic Module files no more than a couple lines
long, with most of the functionality computed on the fly in a header
file based on the platform and path to the Module file. We can even
throw an error if, say, a particular piece of software isn't available
for that platform.
