I asked the original poster what license was the code under, as I started rewriting bits of it to be more.. Perlish.. and wanted to be able to release my modifications under the proper license.
I ended up ripping off completely the part that distributes to accounts, and had been running it for a while locally. All was good.
Unfortunately I kept getting a high number of stales/rejections due to the network code that deals with sending proof of work, which is a bit awkward..

I had been thinking of writing something similar using more modern modules like AnyEvent, but lacked the time. Will likely do this if there is enough want.

On the other hand, I went instead to a simpler system which periodically checks which is the best pool to switch to, kills the miner and has it switch to the chosen pool.

I don't think everybody needs both the pool-hopping *and* the shares distribution: I'd be creating the pool hopping thing only, for one to use with their own miners.

I am not entirely sure if the idea of having multipool sites "up" would create problems for the pools, as a number of GHash suddenly start hopping from one to the next.. with what has been happening as of late with DDOSes on the pools..

Still, if anybody is running multipool locally and needs a hand with some small fixes to the current multipool code, I'd be happy to oblige -- PM me for info.
