modestMap supports flex? i thought it was just AS2? back to the original question, we've experimented w/mapserver via coldfusion/mapscript using flex (but this was a very old version of java mapscript that worked w/an open-source mapscript CFC). see: http://mapserver.gis.umn.edu/docs/howto/coldfusion for info. if you don't want a serverside app like cf talking to mapserver, i think you might be able to get at it via OGC Web Services (WMS). maybe a good place to start: http://mapserver.gis.umn.edu/docs/howto/wms_server/ other how-to's: http://mapserver.gis.umn.edu/docs/howto we've built production systems using flex against esri's arcIMS (again using coldfusion CFC to talk to arcIMS's java connector). it was fairly easy.
