LCD restrictions

thanks guys I'll bare it all in mind,
I've got an idea for my first project when my board eventually arrives from Fleabay
this project doesn't require a connection direct to an LCD but what it could do with dealing with is a video stream either carried by wifi or blue tooth from a mounted camera.
if possible 2 concurant streams.
Sorry if I'm begining to get anoying but will the arduino handle that?
