Alternatively, if someone in Boston has a house big enough for 20 people and a projector, we could perhaps do it the day before Readercon.

See reply above to sairaali—I don't see a practical impediment to performing at Readercon provided it's on the free night, so that Kickstarter backers don't have to buy Readercon memberships if they weren't already coming. The only drawback I can see is that a lot more people might want to attend if they heard about it, because seriously, Old Norse epic.
