When will companies start receiving tax breaks for letting employees work on open source projects? I'd thought about Sourceforge becoming its own non-profit, which might help, but I wonder if [sf.net's owner; I forget atm] would ever go for that.

Still, if it costs companies, say 10-30% less for employees to contribute to open source code than closed source, up to a certain amount, well, we're on to something, aren't we?
