@Chip Bennett -

Ok... as I view the membership plans (which I've looked at numerous times before you provided the link), I am unable to "get" it. If I pay for a 2 site license... I am technically paying for support and updates for 2 sites for 1 year, but... am I free to use the code on as many domains/sites/blogs as I wish? I ask, because that information isn't clearly defined, and actually looks like a "no."

I believe I saw a screenshot that showed BackUpBuddy requiring a user to enter the domain that the software was being used on. I would assume that is to "phone home" and check that the license covers operation for said domain in order to function. Does the software do this? If yes, doesn't that prevent me from redistributing the plugin as I see fit, as required by the GPL?
