This is a very reasonable proposal, and will definitely increase adoption since BTC XBT will again look cheap.

Sooo... I wonder if bits is still useful for nickname or xbit? Exhibit seems too many syllables and doesn't flow smoothly for saying a lot. I kind of

@AstroChicks question about "who has authority": stop asking for authority, don't ask for permission. Anyone is free to use whichever unit they wish. However note that there is strong opposition both against the specific name "bits" and also for "changing the unit and confusing people". Whichever unit will be used, it will be a decision made by use.
