Does anyone question the name BitcoinZ? It may not be the best name for the coin. The letter Z donates the last of the last. This title may bring up negative connotations if Bitcoin ever goes totally south or gets tarnished. People may not want to be reminded of the name whatsoever as more coins are adopted. I know you are trying to make it Bitcoin2.0, but including the entire name BitCoin in it seems odd and people are going to question what it is.
Why don't you call it TidBit, or something creative? TidBit works pretty well actually and supports the loss of all the .000000001 issue.
