From what I saw on cccamp, the network does not tolerate udp multicast stuff? At least my machines didn't see each other... Or does anyone have differing experience there?
Anyhow, a simple wifi hotspot should do. Does anyone have experience how a regular android hotspot fares when it has let's say a dozen devices connected?
