Regarding USD 6,-: Why didn't you people test the free version of Limewire2 before giving away money? I am happily testing Limewire2 for free (with ads) on Mac OS X.

Regarding Ultrapeer: I usually about 5 Ultrapeer hosts. My search result are about the same as with Limewire 1.x (ymmv). Maybe we need to wait a little until there are more Ultrapeer hosts. Version 2 must spread first.
