In multi-tier apps, typically you can survive by only installing the BDE on
the server machine. When you do this, TSession components on the client
don't have a BDE DLL that they can call to fetch this information. However,
there will be a session control on your remote data module that can assess
the alias information.

You could add a method to your remote datamodule that fills in an array of
strings. The client side could call this method, and then take the resultant
strings and add them to the listbox. On the server side, the remote
datamodule would call the same session methods that you are used to.
