1. Keep it simple and bloat free.
2. Very important to me, but if it's binary only and I have to use WINE in order to run it I'm not that interested.
3. Group and community features in a decentralised environment. This includes publishing/broadcasting features as in AudioGalaxy. Permanent identities (public keys) linked to rewards and improved social standing. The ability to use any web browser to browse through verified hash links hosted on the p2p network itself would be nice.
4. I probably wouldn't pay more than $10. I think anything more than that will have a negative psychological effect on almost anyone. $10 is also a reasonable price for foreigners, such as myself, to accept. However, I'm biased so if it's not free, as in libre, I won't pay for it.
Asking for donations would work for me but I don't know how others would feel about it.
5.
Don't PM me about it though.
{P.S. do a search for TankGirl's posts on this forum, particularly her one on permanent identities and the Ultimate Grid.
