Sure, that's exactly what I was thinking of, as well.  The dreams of wealth beyond avarice -if only BFL would deliver, or Avalon would deliver- were still alive even a couple month ago, right?  Equipment that would pay for itself in a few weeks, and pay the mortgage every month thereafter, that sort of thing.

My only point about Bitcoin Edison is that, for entities with low marginal cost hash power, and deep pockets, and ways to control or manage the fungibility risk of bitcoins, this is still a fairly high volume, high profit margin business.
