$2.99 will get you a 15 foot (~5 meter) USB 2.0 cable

theres also 16 foot cables, with a buffered repeater on the end, of which 5 can be chained for 90 feet. no idea about latency in this case..

plus, it will power the device.

what about MIDI over bluetooth? i'm thinking OSC over bluetooth, and a rechargable AA battery in each device, so long as thats enough to last ~1 hr
