The coolest keynote “sex on a stick” moment was probably when Scott Guthrie showed how you could set a break point using Visual Studio Orcas on Windows in Silverlight project .NET code, run the Silverlight output in a browser on a Mac, attach to the remote Silverlight instance, and break in the debugger on the Windows machine when he clicked a button on the Mac…

It’s really hairy down in the machine debug processes, and getting that working cross-platform ‘was not easy’ as Scott said.
