ASP Driven Video Messaging

We have an ASP-based website and are looking for a coder that could implement a one-to-one option of live video instant messaging. The idea being that each member of our site has a profile (which is already completed on our site) and we'd like to add an optional "Click here to initiate webcam chat". The actual scripting we need is a popup window which displays and relays the person's webcam to the user, and includes a text bar in which the user and webcammer can interact if they need to. Adultwork is an example of the type of system we're looking to implement.
