IPC::ShareLite is pretty easy to use, assuming you're running on a box
with sysv ipc (generally, not windows).  Using ShareLite would involve
storing/serializing the object to a location where another process can
retrieve it, so it's still not "sharing" in the sense of two processes
concurrently accessing a single object.

If you can't use IPC, you can mimic this by, for example, using
Storable and writing files to a directory (or pipe, or whatever).
Locking/concurrent access issues become a real potential problem,

I don't know if anyone's ever written a solid RPC/RMI-type utility for
Perl (maybe PlRPC?).
