For those not aware, this will link your ENTIRE iTunes library to the cloud. Amazing. Only beta released so far, but here's my work around:
Download and sign up for mSpot movies; leave off CC info, hit 'Register' - it'll say "need CC info blah blah blah" but you're already registered. The registration will transfer to mSpot mobile (mSpot.com) but you can't download the program without the beta code (currently not available), but I uploaded the .dmg. Not sure if this will work (maybe it's protected) but if it does, enjoy!
