ok my $0.02 (rounded to $0.00) is that this was our first exchange and it was over and done within a hour, which I think is pretty awesome... sure there were a couple of hiccups, but I'm sure we won't let that happen again. If everyone's beer was there at the same time, then it might've been over sooner.
The method of arranging sets of 10-15 beers in each room, in sequence, actually worked out well for me. I just made a list of all the numbers and scratched off each number as I picked it.
If everyone was to agree to 500 ml bottles, I don't see why we couldn't bring it up to 40 people. I'm sure there will be more interest as we do this again. However every three months might be pushing it (I'd still do it), but twice a year is definitely doable.
I also liked how everybody just brought whatever they felt like bringing. There's some styles in this exchange that I probably won't ever make myself, but this way I'll still get to try it. I think we'd lose that if we all made the same style, or even if we all used on ingredient, or one yeast... I say let everyone play jazz, and let's see what comes of it.

This is my signature. There are many like it, but this one is mine.
