I'm interested in getting some ideas and suggestions for a server architecture for a real time geosocial app. One that tracks at the very least user locations live.
Are there any stacks that favour this kind of information? Java Servlets? Darkstar/RedDwarf? Others that I'm maybe not aware of? Live connections to clients and the ability to push updates out to mobile devices is obviously important, although I'm quite new to designing such requirements out.
Thanks!
