Whoops, I definitely miss-read the portion on services vs service processes. The beta had no concept of service processes, it would just scale out from the single service for you. I'll edit my parent comment to reflect that.

... Which now that I think about it, makes extra sites even more expensive. Beyond the 4 I'm already using for a single site, if I wanted to add a single new service for a site to hack on, I'd have to upgrade all the way to Enterprise (with all the cost it would entail). Ugh.
