[Mono-list] Recommended MySQL Data Provider?

Please take a look at:
http://www.gnu.org/licenses/gpl-faq.html#IfLibraryIsGPL

It states:
«*If a library is released under the GPL (not the LGPL), does that mean that
any program which uses it has to be under the
GPL?<http://www.gnu.org/licenses/gpl-faq.html#TOCIfLibraryIsGPL>
*  Yes, because the program as it is actually run includes the library.» So,
I guess I was and I am right.

If I remember right, there is something called FLOSS (or very similar) in
MySql license that allows you to release your application (the one linking
to a MySql licensed library) under a license compatible to GPL *and*
approved by that FLOSS. Not sure what that means but I assume that you can
do a LGPL library that used .net connector, thus allowing other to link to
your app with any other license, including closed-source.

There is a workaround that I was told to work well - to make sure your app
works with other providers, like postgres, sqlserver, access, etc.... and
load the provider dynamically, that is, as an addin (using a xml file and
reflection....). Again, I'm not sure this works, but I believe so.
