I think one problem with something like a Mirapoint is that with 160,000 + users, per user licensing becomes really expensive really quick. If its per user license were more than a few dollars, the cost of the system would balloon and that's not even considering the cost of storage yet. I used to work for a smaller university that considered a Mirapoint and with ~7000 users we were looking at a pretty expensive system after everything was figured out, and that was using our own storage. Unless the price is reasonable, per user licensing on a system our size can be prohibitive. --Ray
