I myself am a big big fan of the Gnutella P2P Technology,
I am coding a hostcache for ASP now.

Gnutella is great but how come I usually cant
download anything? I am running Gnutella to be a
node for the network but not for downloading because
downloading simply sucks on Gnutella.

Look at KaZaA:
There usually every download request ends up successful,
and you can search the id tag of mp3s and other documents.

Why cant I do it in Gnutella?
Failed downloads usually dont resume and the
downloading from multiple hosts usually doesnt work.

For me Gnutella looks quite Beta compared with Fasttrack.
How come?
