Answering that would require an explanation of how the peer-to-peer Wi-Fi 
protocol works.  Alas, that's not possible because it's a) not documented 
publicly, and b) too complex to permit a short explanation in email.  
Regardless, from your perspective it doesn't really matter: peer-to-peer Wi-Fi 
works the way it works and there are no knobs that you can twiddle.  The only 
thing you can do here is file a bug report, but that's not going to yield a 
solution in the short term.

Right, but that's subject to the limitations of the peer-to-peer network links, 
which is where we entered this discussion.

I think you should try out NSNetService with includesPeerToPeer to see if that 
helps at all.  My guess is that it won't (Multipeer Connectivity is implemented 
on top of NSNetService, so the peer-to-peer network link limitations tend to 
apply to both) but it's sufficiently easy to code this up that it's worth 
testing anyway.

Share and Enjoy
