i can't give a cost, we're not in a commercial forum... i can't talk about quotes or else... i just say that we can use such a software and integrate to vB for a certain cost... you know a specific product that answer your needs, we can deal with the integration if it's in php/mysql...

btw, i will take a look at the commercial softwares that do most of your requests, and see if you can deal with a Group Project... if the software cost 100$ for an unlimited domains, i may be able to offer something similar ported to vB... also, i can contact a code creator to make a deal with 'em and make a complete recode to integrate to vB... but usually, this is not free...

i had some suggestions lately (last night) and i think to be able to provide a commercial web-cam portal in begining of august... point is that it will not answer all your requests, but once a basic system is built, any coder can create addons for it...
