There will be multiple bitUSDs from multiple DACs from outside and inside I3. We know this.
So the question then becomes what is best naming system?
bitNOTEUSD ? noteUSD ?
On some level it would be nice to have them suggested as part of the bitshares family, but I don't think that can reasonably be done. I assume the answer will be something like noteUSD/voteUSD/bitUSD/jdsUSD
