Simple question, many answers.

Also, don't ask this question so soon, it takes time to review code, and even more time to find vulnerabilities and come up with working exploits.

Second also, P2P system inner working are much more complex, and can be vulnerable to some other types of attacks which are specific to P2P protocols.

Having decent P2P security is not really easy. P2P is really exciting, and the advantages are great, but I don't know the specifics of P2P security.

Bittorrent and bitcoin can seem simple compared to a P2P messaging program.

TLDR: It's the future, but it's not exactly there yet. I'd still use it with those vulnerabilities though.
