One of our customers needs a cross platform message client on their desktops. It has to be cross platform (at least Win32, Linux) and really only needs to display a popup alert box with a text message and clickable URL. Each client has a static IP address and messages would get pushed from a single server. We're not talking about many messages either - probably a few a day at most.

Anyone know of an existing solution that would do the job (any language, not just perl!) The alternative is we knock up a Win32 service/UNIX daemon using something like Tk and NetServer::Generic - as the desktops tend not to be rebooted often, my only concern with this would be memory usage and the possibility of resource leaks over time. Again if anyone can give some suggestions about going down this route I'd be grateful.

Thanks
