The whole calling home to a remote server which manages the rigs and "directs" them to a pool of user's choice is a deal killer.

Like I said in an earlier post, this functionality could be useful if the user retained control over the actual control/head server sitting at the top of the rack, instead of having it hosted. Anyone spending $30,000 per unit for 40 units can damn well spend another $500 on a cheapo rack mount server to run them.
