Thanks Mark for your answer! If you're using only OpenSER and Asterisk, this means that you pass all your calls through Asterisk and use openser only for authentication and proxying. Is that right? How do you make the calls pass through in NAT environments? Is Asterisk capable of handling that? How?
Too many questions... i know... but i'm excited with that possibility...

We are running a similar operation but settled on just OpenSER + Asterisk. All media runs thru Asterisk so MediaProxy isn't required and a custom billing engine was easy enough to put together. Yes it uses a lot more bandwidth and CPU but the combination of accurate accounting and easy NAT transversal make it worthwhile for us.
The total number of subscribers isn't an issue (there are just entries in a database) there is no difference between VoIP<>VoIP and VoIP<>PSTN for us as both are SIP connections. We haven't maxed our initial Asterisk box yet but anticipate that it will handle about 200 concurrent calls depending on codec translation. A single OpenSER + database box should be able to handle several Asterisk boxes.
(I'll also take comments on above, thanks)

Yes. There are some liabilities with that in that the signaling messages may be incomplete (i.e. you may miss a BYE) and this is the usual reason given for doing media proxying for more accurate accounting.
But the latency, bandwidth consumption, and increased complexity and cost associated with doing it on a large scale does not justify it, in my opinion. SIP-only accounting is "good enough" most of the time.

Without mediaproxy? Only based on SIP messages?
