Flood the world with Bitcoin-ish currencies.

Not Bitcoins themselves - that can't be done - but other crypto currencies. The way to do that is to make it as easy as possible for people to start their own currency with it's own genesis block, that will play nicely with others and, of course, Bitcoin itself.

Yes, I know Multicoin has taken a few steps in that direction, but what we really need is a turn key solution so anybody can do it.

The utopian solution would be for the Bitcoin client itself to have an option 'Start your own currency' that will accept a currency name, a starting statement, a time-between-blocks argument, a blocks-per-difficulty argument, etc.

When done, it would automatically create the genesis block and wallet in a new directory and start mining.

Also, there will be a way to let others just get the particulars and begin using the new currency, if they so choose.

This will cause a new problem, a million little idiot currencies, but it will swamp the people trying to destroy Bitcoin, so we will have traded a potentially fatal problem for an annoyance.
