After some discussion on #mono it seems like MySql simply isn't being clear.
The ByteFX implementation is fully managed, it doesn't link to any mysql
libraries. From mysql's website:
"When you distribute a non-GPL application that works only with the MySQL
software and ship it with the MySQL software. This type of solution is
considered to be linking even if it's done over a network."
That is the only questionable claim that they seem to make. It seems kind of
unreasonable to think that just the act of talking to a MySql database could
cause you to have to GPL your program. ByteFX would fall under this clause,
if the clause is even something that the GPL specifies.
