Can't really speak to front projectors because I haven't researched them.

However, one would suspect that you wouldn't want a "mess" of cables run to it. So, in your specific case, maybe swithching in the receiver makes sense.

Would 2 HDMI inputs be enough or would you want 3 HDMI inputs just to be on the safe side. That third input narrows the number of HDMI switching receivers.
