Since there seem to be a lot of "I'd love to, but not ready until X" responses, why don't we set some future date so people could actually target it and brew/package appropriately?
Better yet, why not do it quarterly (or monthly, even)...whoever's ready participates, everyone else waits until the next round.
[EDIT]: BTW, I'd love to participate. I'm always thinking my beers are either God's gift or utter crap (probably/hopfully wrong on both counts), and I don't really trust the people I see day-to-day to give me honest opinions...)
