I just got off the horn with the excellent Peter Suk (he of Ruby to Smalltalk VM porting fame) and found a place for the Houston Rubyists to roost: Tuesdays at The Stag's Head Pub in Shepherd Plaza at 2128 Portsmouth. Be there, or be like a static programming language.
UPDATE: Peter pointed out the wiki for his VM project. However, it's timing out for me.
UPDATE: Well, I didn't make it. My date rang long (a better excuse than many), so I owe Peter a decent draft.
