arduino net control?

so heres what i had in mind...im a puppet/toy maker...im thinking of creating a 'real virtual' game...where the characters and setting are actual, physical objects, its captured on webcam and controllable over the net... With the hope of forming an online community around it. The physical aspecs of the idea are easy for me...as are the mechanics...but the techo-digital aspects are a tad more new for me...i can and have coded games before...ive used arduino for a 'tagtool'...but never dived deeper into the potential of arduino than simply copying the required script and downloading it into the unit made following a clear step by step guide. So as you can see...my idea is more a pipe dream, but i wanna explore the potential using things i already have some experience with.
So any guidence, or help is greatly appreciated. Maybe someone with a super arduino brain would like to team up with me on it???
