You say the "ENTIRE FILESYSTEM".  I have a question for you.  If I have
a DBMS physically on one machine, can I run an application against the
database on the remote machine?  Assuming I have a way to tell the DBMS
what the path to the DBMS is.

For example, INFORMIX-ESQL/C.  If I specify on the local machine in an
environment, DBPATH=/u/whatever, will the application work if I
specify DBPATH=machine!/u/whatever?  Anyone know the answer to this?

What kind of performance degradation am I looking at?  I would think
a DBMS would not care where the data is comming from, and the request would
be mapped to the device driverat the kernel level where the tcp/ip stuff-ola
is happening?
