Neither of those two examples give away their core software for free though, which sounds like what Simperium are going to do.
I'm absolutely not saying it can't work, and kudos to Simperium for taking this approach, it looks like there is an absolutely great product there and I'm going to be checking it out.
There are of course examples where this does work, RedHat for example (heh - I do it myself as well!), but I was wondering if anyone has tried to look at it analytically, or is it just a gut feeling that this is the right approach to maximise revenue?
