[PATCH] increase block size limit

We should be able to at least match Paypal's average transaction rate...

Applying this patch will make you incompatible with other Bitcoin clients.

We can phase in a change later if we get closer to needing it.

IMO it's a marketing thing. It's tough to get people to buy into a system, if the network is technically incapable of supporting high transaction rates.

Satoshi just said it can be changed, so technically the network is capable.

It is also an incompatible change, as you see.....

No, it's incompatible if just a few people change their behaviour. To roll out a change to the network you need to get most of the clients understanding both the old and the new protocol, and then when you have a majority you turn on the new protocol.

You just described a whole-network upgrade. I'd call that an incompatible change 
The effort to raise the transaction rate limit is the same as the effort to change the fundamental nature of bitcoins: convince the vast majority to upgrade.
