What would be _PERFECT_ is if ixcoin's original block speed target was at least mostly met for a while. Then (especially uninformed) people would never upgrade. And many ixcoin.2 people would switch back. Then throw as much has as we absolutely can get (Hey, Artforz, want in?) for a couple weeks... get difficulty _WAY_ up, then all abandon simultaneously one block after a difficulty adjustment.

The two block chains would be nearly impossible to reconcile because Thomas made them two different p2p networks and protocol versions. And ixcoin.2 would be mostly abandoned and ixcoin.1 would be retargeting in 2150.
