if we are going to use some IPC mechanism, I'd go by adding a
GdaCORBAProvider, and then use CORBA for MySQL, and then also add a
generic CORBA provider which allows to access the 'normal' plugins via
CORBA. This would help in using libgda for distributed systems, and will
also avoid the 'how to activate the external provider' problem.

This (the generic CORBA provider) is something I had in mind for a long
time, so maybe we can take advantage of the MySQL problem and do it.
