[OpenLayers-Users] Displaying moving symbols on a map?

[Okeefe, Charlie (Mission Systems)]

Thanks Andrew, I'll have to look into that. I wasn't too worried about
that aspect though, since it is fairly easy to create a timer using
javascript to periodically check for updates...

Yes, I think that this approach would make sense. Your server-side code
can emit some javascript code to reposition a marker. PeriodicalUpdater
could intermitently be called with the url of the server code the return
of which would be eval'd by the client on return.
