well, we were using an IPC mechanism before (CORBA) and we removed it
because it wa spreventing libgda from being used in a lot of places. It
wasn't slow at all, but because of the dependencies, people didn't like
it very much.

We changed then to a shared library approach, which has been the key for
libgda being used in Gnumeric, Abiword, Planner (in a few weeks :-),
etc.

What we can do though is to have a GdaLGPLIncompatibleProvider base
class, that communicates with the real provider by some form of IPC
(CORBA, local sockets, message queues, ...). Then, all providers that
gives us this kind of licensing problems can use this base class.
