I had a bit similar situation and ended up not calling the pop-up from 
our server, but using document.write in the script the clients include 
on their pages. This way the pop-up can communicate to the opener.

In the included script I have a function to receive the pop-up's window 
object, and the pop-up calls that with an interval. If the user browses 
to another site and then returns to a page with the receiving function, 
the connection is restablished. And to avoid javascript errors while the 
user is on another site, I've wrapped the calls from pop-up in a try {} 
catch {} block.
