    I have tried to install the pathalias and uupath software on our net and
    have come across a few problems.  Before I go in and hack the c source,
    has anybody out there tried this yet and found solutions to the problems?

The only problem is that you run out of sbrk space.  Unix programs assume
that sbrk space is always contiguously allocated, which is mutually exclusive
with a rich mapped address space such as is provided by aegis.

Here are the mods I made to pathalias to get it to work:
