Gavin and the community will take any improvement your new wondercoin offers, adopt it for bitcoin and things will be fine. Bitcoin is not set in stone - if there is a consensus that something needs to be changed, we have the technology and the motivation to make that change.
Nope, Bitcoin as a protocol can't function for instant transactions, it needs to be reworked from the ground up, pretty much creating a new crypto currency, by the time that happens, if it ever happens, the new "wondercoin" has crushed it.
Just Like AOL tried to finally catch up to Cable internet by offering it's own High Speed Option, by then it was too late. You don't have to be a genius to realize this thing is way to slow for real transactions, the fact that they haven't done anything to it for the last 5 years shows how amazing Gavin and the community is lol.
