Is Screen Pop Supported or Support-able In BUI?

Content

I have a client who's running the .NET Agent Console, and is thinking about moving to Agent Browser UI (BUI). However, they're also using screen pop, and they may not be able to make the move unless BUI supports screen pop.

Experimentation on a test site has shown that screen pop doesn't work in BUI. It's possible I'm overlooking some configuration, but it occurs to me that listening for and responding to requests on a localhost port would be kind of a strange thing for Javascript-in-the-browser to do. I've spent some time searching for ways to do this and come up with nothing, so it's not looking good at the moment. If this isn't possible with browser Javascript, that would pretty well put the kibosh on screen pop for out-of-the-box BUI
