Wendell,
Even if you had, say, a beta copy of 5.1, even without going down the alley, I would hesitate to install it on a network with 15-20 clients.
Because, even if all was good, as soon as 5.1 gold drops, then the IT elf [bullwhip or no] has to go deal with all those machines again.
I think that besides getting our current mobile app released, I might work on an app that used the accelerometer to simulate a bull-whip on my Droid-X. Yep, that definitely sounds like more fun. Bet I could get Bert to install THAT app.
