Enough people pay for Pro that LW can support more than 7 full-time developers http://www.limewire.com/english/content/team.shtml , AND LW can release an opensource client for FREE without having to fall back on ad-support.

Sheesh! spread the word and get your friends to help these folks support development for as much as they can, while they can.

With 3 million LW users estimated currently, $10 from 1% more can support much more development.
