Bob, Thanks for this note -- always glad to have more discussion about this. I don't know if you remember a Bell Canada commercial from the 80's that featured four businessmen, each in different locations, starting what looked like a teleconference. Ended up, they were actually a barbershop quartet using teleconferencing to hold their practise. You're right, that due to the latency, this really wouldn't work. However, the plan is the chorus would be in Toronto, and the coach would be in St. Louis, MO -- so the latency wouldn't be a significant factor. I have multiple alternatives to Skype, and the suggestion to use a Rogers Rocket Stick is a great one, so I may go with that. I really appreciate all of the comments -- thanks again, all!

If you're trying to synchronize singing between different locations you'll probably find that even the fastest connections have unacceptable latency. Imagine there's a .1 second lag between you. When the conductor says "Go" the group in the same location starts immediately, but the remote group hears "Go" at t=0.1 and by the time the local group hears the remote group start it's t=0.2 There's no way to synchronize two choirs in different locations (although someone may be able to synch separate soundtracks in post-production).
But, you may want to try the Mumble client (or Plumble on an Android device) using a Murmur server. Mumble allows you to record each remote connection separately in its own sound file for post-production processing.
Mumble /Plumble / Murmur is an audio-only solution, no video. There's a text chat channel, tho.

Hi all,
My chorus is thinking about having a coach work with us over a Skype connection, with the catch that we rehearse at a church whose WiFi we're not allowed to use. (It's complicated.)
It would be possible to use a cell phone as a hotspot, but I'm not sure if it would provide enough bandwidth for the call. The rehearsal would be about three hours, so at 128kbps (Google's answer for Video calling), that would burn through 135M, so about 1/7 of my monthly allotment. Then again, video isn't necessarily required, and that would cut down the required bandwidth to 30kbps.
Are there any alternative products or services that anyone could suggest for this type of application?
