Well, my 2 cents, picture transport protocol is so obviously different 
than flags for network interfaces it does not cause a mental collision. 
However P2P is about to become a huge wifi issue, which definitely is in 
the network space. So don't confuse things in the near future, don't use 
P2P.

Maybe a completely different, not so overused flag name would be better.
