With the upcoming 5th version of Silverlight, can we implement a p2p Silverlight OOB application? If so, would it work on both Windows and Mac? Life would be a lot easier with WPF, but I like the fact that SL is not limited to Windows.
P.S. If no OOB is an option, that's even greater.
Nope. No p2p support in SL5 I afraid.
