Maybe; we've got a lot of Android clients on the network, and I'd 
assumed any bug would be more widespread, but I guess given the 
diversity of hardware and OS fiddling that goes on, it might be feasible 
that only 2 of ~3000 hosts would be affected.

Maybe I'll try and identity the client OSes more accurately.
