you can get this functionality at the moment using windows networking.
interbase is kind enough to detect that the file is residing on another
machine, and redirects all requests for that database through to the correct
server. (i found this one out the hard way).
so if you map \\server\servershare to s: for example. then connecting to
s:\test.gdb will actually connect to the server's interbase server! path
hiding.....+full security if the share is sitting on an NT box.

answer to a msg from mers.interbase.list..

I Agree 100% on this one. It is keeping me from changing names on my
databasefiles bc i would have to update all the clients, which should not be
neccesary.

Someone with time to spare might look into some kind of alias system. It
could be implemented as some kind of parser method that recreates the path
from the connectstring. if a client connects with a string like
servername:aliasname (no drive at the start, exact syntax to be discussed)
the new feature should figure out that an alias is being specified, and look
up the physical path from an alias list. The physical connect string could
then be sent to the old server code that connects to the database file. A
small API should then be developed. add alias, remove alias, alter alias,
and get all aliases. Someone then should make a cmdline app. to do these
changes, and someone might do a gui app too. I am currently only fluent in
Delphi, so i can't really do any programming besideds a windows gui.
