thanks roger

I see it this way... why not spend 5 min on an e-mail... worst case is that they reply that they will not give away the rights... but maybe they say go ahead... or that they want some money for the rights...

in any case it only took me 5 min to ask

but i like to be one step ahead.. what if they just give away the rights? should the source then be complete free or should there be some kind of control?
