Auto-Refresh

Wondering if anybody can give me any ideas as to whether or not this can work in a portal environment.

There is an open source solution for auto-refreshing called pushlets. On the client side, it basically is an HTML page with two frames. One frame is the display and the second frame calls a servlet which subscribes to a certain subject (through a parameter). When a response is returned from the servlet, the response calls a javascript function in the main HTML page to refresh the display frame (or display new data from the servlet response). I've already proven that these pushlets work in a non-portal environment...However, I am having trouble trying to integrate it into a portal environment.

Any ideas???
