So throughout this whole Zune launch thing the whole lot of us have been playing cat and mouse with Microsoft on the finer points. Will it or won't it be built on PlaysForSure or some variant? How will it recognize copyrighted vs. creative commons content without opening up piracy loopholes? And perhaps most importantly: how will the wireless work? Well, it turns out that a Zune employee by the name of David Caulton thought it'd be worth putting together a cogent explanation of what the Zune wireless connection can and can't do.
Can search for and find other Zunes nearby.
Can send songs / albums for the 3 x 3 trial. Songs past the three days / listens are deleted at next sync, but catalogued on your PC for record-keeping should you want to purchase them later. No word on whether Microsoft is going to keep track of which files are traded.
You can send and receive image files for "unlimited viewing." (Oh, so copyrighted images aren't worth DRMing?)
Connect to the internet.
