Corba is just one method of implementing this. There are many many
protocols which we can use (we could use ONCRPC, we could use COM, we
could use our own homegrown protocol). Really, it's a question of the
requirements and how much programming you want. I admit I'm not a fan
of CORBA (but I'll also admit that I don't know much about it).
However, it sounds like it's just another RPC-like language.
Another way to have multiple users is to truly separate the gui,
engine, and filestore.. In such an architecture, the filestore could
be an SQL server with SQL queries and events (IIRC, SQL allows
asyncrhonous events from the database). Or, you could add a small
shim on top of SQL that actually registers callbacks for event
notification...
There really are lots of ways to implement a solution. CORBA is only
one. First, come up with the requirements, then an architecture and
design, and then we can think about what pre-existing tools we might
want to use.
