Need a solution to show full-screen pop-ups

Hi everyone,

My organization just chose to use Openfire to run a chat service and we’d also like to use it to pop up messages full screen to alert our users. So far I’ve checked out several clients but none of them seem to support what we want to do. Short of writing our own plug-in, does anyone know or use a client or plug-in that would support this functionality? Basically what we’d like the end result to look like this: one of our managers can send out a pop-up to all users with a certain message or messages full screen or centered on the screen big enough to annoy people enough to read it. Any vibrating or motion would be great too.

Thanks for helping out!
