There’s an unusual “theory” type thread going on here on the MSDN forums: http://social.technet.microsoft.com/Forums/en-US/sharepointgeneral/thread/34d11f89-4405-4ba5-b0f0-faa5af6e6ad5/
A lot of MSDN forum questions are very “how do I do [x]” in nature.
This is a big topic and some of the key issues are being addressed pretty nicely in the thread.
Join in the fun!
