Control/Data flow scheme

I could do this a zillion ways, but this is how I've settled on it.



Basically, users connect over the net to my house. My router forwards the correct traffic over to the land raider via WiFi. The land raider meanwhile is sending data (mainly images) back the same way.
What I still need to decide on is if I want to do this with some browser based method (like what I have currently setup with Serial Host) or if I want to write my own application that runs on the remote computer. Maybe I can find an easy way to do both.

Getting the images/video from point to A to B is going to be the hardest thing, right now I'm just using some crap webcam software that updates every 1/2 second.
