A small correction; until the beta is open to the public, the beta users are not allowed to post code that uses the 6.5 SDK extensevily (like a medium big project like this does). It would expose the new functions and ways of the 6.5 version, which we dont want to make public just yet.
Binary 6.5 projects or 6.5 dlls are not allowed to leave the closed beta program.
But 6.5 screenshots are allowed to be posted publically without worries, as seen before

!
I hope this cleared it up somwhat!
