My intent is not to cheat Mysql here - I can assure you of that. It 
certainly wont decrease their sales and in fact if Gnome used it it 
would probably increase both their profile and sales. If it was harmful 
in any way to them then I would accept your point. IANAL so yeah there 
may be issues here I do not understand.

DDS will only use a fairly limited subset of Mysql API - im not planning 
to duplicate the same interface or equivalent functionality of a 
libmysqlclient via DBUS. DDS simply uses mysql as a back end data store 
and its API will not be influenced by mysql's. As it does not provide 
"all the same functionality normally given by static or dynamic linking" 
it should be okay.
