I'm curious about how you're doing per user pricing. If the source is open, how are you enforcing limits on the number of users? Is a portion of the code base closed source? Or are you just using the honor system? I'm asking because I sell hostable software too and I've been thinking about per user pricing for a while, but I haven't made the switch yet.

I just released the beta version of the site so I don't have any data-points yet. But I'm hopefully going to bank on enterprises mostly purchasing the software, and those are going to be entities that I know will most likely respect the per-user contracts. The entire source-code will be available to the customer once they purchase the license. I've had to make a lot of hacks when tailoring 3rd party software with pieces of their code closed-source, so I hope to alleviate that pain for other developers.

What type of software do you sell, and how are you currently charging clients?
