non-hardened environment variables in IFDs?

Is it possible for Houdini to *not* expand environment variables when
writing to IFD?
More generally, what options are there for dealing with relative paths
when moving from one's local machine over to a render node? For a given
project, I tend to create a directory tree with one or more .hip files
in the root folder. Resources are then referenced as $HIP/shaders,
$HIP/maps, etc. In the ROP, I'll then prepend my output filenames with
$HIP/render/diff, $HIP/render/spec, etc. This works great on the local
machine. However, writing to .ifd, the $HIP (or any other environment
variable) gets expanded. My hack is to run a post-render script that
does a search/replace of the hardened strings, converting them back to
envvars. Of course this only works with ascii IFD.
I'd be very interested in hearing how others deal with path issues ...
Cheers,
Darran.
P.S. I've got a nagging suspicion that I asked a similar question on
the list last year. Can't find a reference to it in the archives though.
