Scott: They claim 80 meters without obstructions. Probably translates to works OK if units are within 20 meters of each other with obstructions. They don't list any meaningful specs about speed. However it does operate at 2.4ghz which is the same frequency as 802.11g which broadcasts at 54MB. Midi 1 is only 31.25k. Hopefully they have enough bandwidth.

My other concern after reviewing the specs is that the unit is either battery or USB powered. If you are using an unpowered USB port you will need a case of batteries (they state 20 hours battery life with use). Hopefully it can take a power adaptor as well.
