Yes - I can see that running an event on the same day as MFS would not be very diplomatic (I think I undestand a little more about the intergroup dynamics now).
That means a meeting the same week as the JACK talk, or delaying two weeks until the first week of April
I'm fine with either. We could always kick things off online to start with. Maybe use a shared space on dropbox to exchange code examples (if dropbox usage doesn't conflict with anyone's principles).
