[DotGNU]Selling support and ModRequests for dotGNU

[Charles Shuller]

This is a bit of an ethical question, the GPL as I understand it makes 
this legal, but say so if I'm wrong.

Is it ethical to sell support contracts, and mod-requests for dotGNU 
even if the person involved is not necessarily a primary developer?  And 
can/should the resultant code be put back into the codebase?

I'm thinking of advertising this service in the near future, when I get 
a LOT more fammilliar with what I'm doing, and want to make sure that 
this is not something which is severely looked down on, or downright 
illegal.

Thanks!
