Cool. I thought it would still be early enough to make non-breaking changes to the algorithm (are there allready many other implementations out there?) and didn't think you would be in favour of other flavours of the firstbits idea due to the risk of confusion that you mention.

But if you are not opposed to the idea, I think I might have a go at coding a transferable decentralised address alias. Might I push my luck and ask if you would be willing to opensource the firstbits code? Would make a really nice starting point.
