Malware request for bots that use P2P for C&C

I am a student at Aalborg University in Denmark doing a research project in traffic pattern detection.

I am searching for bots that use P2P for command & control.

The only samples I managed to find are Peacomm.C, Nugache.A4, and Nugache C@mm.

If anyone can provide me with binaries of or pcap trace from other bots of this type, it would be very appreciated.

Thanks in advance
Søren
