Have you looked at the handheld keyboard-trackpad units that Rii makes? They don’t quite tick all your boxes, but I think it could still be a step in the right direction.

I am quite happy with my Rii I8X. The trackpad exceeded my expectations—I have no complaints. Having it centred makes a big difference, compared to the wobbly experience with the full-size units where it’s on the side.

My one complaint is that I can’t quite touch-type on it. But that’s probably OK if it’s for occasional use with an HTPC.

I think other brands make similar keyboard units with mini trackballs, but I don’t think I have seen any with trackpoints.
