As soon as I get ten NXTs handy, I'll be sure to test this. In fact, I may know
somebody who could test this (or at least I can think of a place, NI Week, where
I might). Very odd.
Try this. Establish five pairs, and then establoish a sixth pair in a different
location (a couple of buildings down the way, or a few floors/rooms away, etc.
Now with this sixth pair set up in a "clean" environment, walk them back to the
group room with five pairs already active and see what happens.
I've used BT remote control in environments with simply hideous numbers of BT
devices running around (NI Week last year... it took something like 10 or 15
minutes to search out all the visible devices IMS), and experienced no problem.
Still, I can't claim experience with 10+ simultaneous NXTs.
