I found a venue -- my employer is willing to host.
I'm provisionally organizing this from 4pm - 7pm on the Sunday of LibrePlanet. The location is in downtown Boston, and we'll have a quiet space, plus phones and a projector for people remotely to call in. I think we'll even have a phone conference number to dial in. There'll be Wi-fi too.
So far, I have:
Matt Lee
Chris Webber
Jason Self
Mako Hill
Bernie Innocenti
As the people who'll come to the office... let me know if you're interested in attending the in-person meeting, as you'll need to be on the security list to enter the building. Photo ID is also probably required.
