I'm not sure what your needs are, but you may want to look into DODS:
Distribution Oceanographic Data System; it's a client-server set-up that
applies to all data types (not just oceanographic). DODS allows
communication between many different API's (IDL included), and uses the
web to communicate between client and server. I think you can set it up
so that the server isn't accessible to anyone outside of your group, but
I'm not sure.
We set up an IDL client on a sun sparc solaris 8. Although it was a pain
to set-up, the rewards are good.
Cheers,
Davida

Or write a DLM on the client side that uses RPC calls to communicate with
the server.

I'd consider using the IDL internal SOCKET procedure on the client side,
and building a TCP/IP socket server on the server side, written in C and
connected to IDL as a DLM. It's not as hard as it sounds. If it's a
local client-server interaction, a pair of named pipes (FIFO's) would
do.

Thank you. I think it would be the easiest way to solve this problem.
