somebody should make a better ICE tracker, for fun.
maybe with ZKP.
maybe over Tor.
maybe P2P.
importantly:
1. it should have a good site that gets the point across
2. it should be easy to use and understand
3. it should do the primary function
&
4. it should fix what you're complaining about the ICE block app (without breaking what the ICE block app already does)
good documentation, PR & UX outwin "more sound designs" every time.
