IPP2P v0.8.2 options:
--ipp2p Grab all known p2p packets
--edk [TCP&UDP] All known eDonkey/eMule/Overnet packets
--dc [TCP] All known Direct Connect packets
--kazaa [TCP&UDP] All known KaZaA packets
--gnu [TCP&UDP] All known Gnutella packets
--bit [TCP&UDP] All known BitTorrent packets
--apple [TCP] All known AppleJuice packets
--winmx [TCP] All known WinMX
--soul [TCP] All known SoulSeek
--ares [TCP] All known Ares

EXPERIMENTAL protocols (please send feedback to: ipp2p@ipp2p.org) :
--mute [TCP] All known Mute packets
--waste [TCP] All known Waste packets
--xdcc [TCP] All known XDCC packets (only xdcc login)

DEBUG SUPPPORT, use only if you know why
--debug Generate kernel debug output, THIS WILL SLOW DOWN THE FILTER

Note that the follwing options will have the same meaning:
'--ipp2p' is equal to '--edk --dc --kazaa --gnu --bit --apple --winmx --soul --ares'

IPP2P was intended for TCP only. Due to increasing usage of UDP we needed to change this.
You can now use -p udp to search UDP packets only or without -p switch to search UDP and TCP packets.
