I suppose that it is possible to allocate a second framebuffer on Omap Gfx, a framebuffer which isn't displayed to internal lcd but of course it is hw assisted by GPU + DSP.

A guide to how to hock up N900 to a computer and the X display "commands"

EDIT:
And for the Record i do grasp the many functions that are available with using the PI with our N900.
This is without a doubt the most awesome Addon to date

I must admit, that I'm focusing on X display exporting, as I wish to stick with something both effective and achievable. Personally, I can live without playing GLES games (Neverball ) on big screen, or using remote desktop explicitly for doing so (productivity things = most of Maemo programs - are priority IMO).

Of course, I'll change mind with pleasure, if Your ideas with video framebuffer encoding/decoding turns out to be achievable, and You - or someone else - come with a working solution.

I can forward the keyboard from another computer and if I use one of the compass point switches even mouse forwarding works fine. But using the compass point switches means that the desktop feels like having two displays hooked up to one computer which usually is a good idea. Unfortunately it is no good idea at all if your input device is a touchscreen and not a regular touchpad because this way you can't leave your primary screen.
So what we need is either an option to make the N900's screen behave like a regular touchpad, i.e. interpreting movements as relative not as absolute (if someone could write a Maemo application that would cover the whole screen and transform the absolute inputs into relative outputs that would be great) or tell x2x to forward mouse movements as long as the cursor is on the x2x window (which I first thought is the case, but it seems it isn't - please prove me wrong and tell me which switch I missed!)

I see a 3rd option:
Keyboard forwarding with x2x works fine, and if we carry an N900, a Rhaspberry, a USB and an HDMI cable and most likely one or two chargers with us we can just as easily add a micro mouse to that, which unfortunately brings us back to our tiny but mighty pocket computer that we call N900 PLUS THE HUGE BAG WITH ALL THE EXTRA CABLES AND ADAPTERS.
btw: If we connect a mouse anyway the only point in connecting the N900 and the Rhaspberry is to spare the keyboard. TBH the N900's keyboard isn't great either so we could just use an onscreen keyboard with the mouse on the Rhaspberry and make that whole thing an awful lot cheaper by simply canceling the N900.

Ok, you might use it to get an internet connection but that's simply connecting it in PC suite mode. Or you want to use the data stored on it? Simply connect it in mass storage mode. If you want both there should be a way in PC suite mode that allows mounting the N900 via network.
