A member of Zuneboards, has created a program to allow your Zune to sync with other media programs.

zAlt2

zAlternator is a program that will allow the Zune to be picked up and synced with programs other than the Zune program. It has been fully tested and proven to allow the Zune to be picked up and synced with the Zune program (duh), Windows Media Player 11, Winamp, and MediaMonkey. I have been unable to fully test the iTunes side of the program, but hopefully it should work.

For more info about zAlternator, visit Zuneboards
