My vote is to NOT change BTC, but get used to talking in micro-BTC (UBT,UBC,uDTC,whatever the concensus), but that's not clearly available in the vote!

I think it'd be suicide to revalue the BTC now, and it'll cause problems with people who don't upgrade old clients. Now that Bitcoin has been featured in Forbes and The Economist and people are trading at $20, this isn't very early days anymore.
