That will lead to the same set of problems currently manifested in bit torrent'ing:
1. You'll have to expose a port externally. God only knows who will attempt to take over it.
2. You'll have spammers advertising addresses of known businesses in attempt to get everyone to spam (initiate connections with) them.
3. Sooner or later people start distributing content not related to Zig, which will attract acute attention from law enforcement agencies.
Consider these to be my predictions.
