Please explain how, precisely, you would forge on multiple Nxt chains at once.  How would you:

1) set up multiple network nodes, with at least some stake forging on each, and keep them from getting blacklisted for bad behaviour
2) learn enough about network topology in real time to understand which forks are being processed on each of your non-blacklisted nodes -- or, better yet, predict which forks will operate on those non-blacklisted nodes
3) successfully exercise enough stake on those forks (hint: you can't move your stake from one account to another, because it won't forge until it's been in that account for 1440 blocks) to be able to forcibly forge enough blocks to create the longest chain, before any one of the other forks (being processed by a much larger proportion of total stake) outperforms you (hint: you've got about 100 seconds to do it, in competition with all of the other active accounts on the whole network, assuming all previous questions have been successfully met and verified, and then you have to start all over from step 1)

I'll wait.
