Potential concerns:
- location of home directories (same as Windows, or in $cygwinroot/home, or=
 somewhere else)
- location of tmp (one shared in $cygwinroot/home, or per-user, or somethin=
g else)
- location of var, for example for apps that put pidfiles there (one shared=
, per-user, else)

Essentially, as with any other shared app with possibly concurrent use, the=
 program directory should ideally be read-only and any user-generated state=
 gets written in per-user directories.

I'm also suspicious of whether advanced filesystem features will work on a =
network path, e.g. deleting/updating files/binaries when in use.
