xenarc sent me a pdf from eeti.com that has some extremely basic info on parsing the data that comes in from the USB/serial port. Xenarc doesn't do the drivers themselves, they just take what eeti.com gives them apparently:

"Please see attached. That is all we can provide. Or you can contact EETI directly. www.eeti.com and see if they are willing to provide you the
source code.

We use their touch solution, so it's not up to us to release any source
codes."

I'll start looking at the pdf, see how far out of my programming league it is. ;-)

So I went and looked on the EETI site and found a download for Linux Driver for their touch solutions.

I'm interested in a solution for an external touch screen for the N900 as well. I've got a project that could use this functionality.

I would like to get away from a tethered solution though and use a wireless control of some sort. But beggers can't be choosers. Even a tethered solution is a positive.

Allthough, native x server is ofc better solution

This interests me also.

I have been thinking of how to implement a larger tablet-sized screen as a car system operating from the N900 to use its maps, music, phone, browser, etc. That would mean that the "car" system would not require its own SIM for internet access, and it begins to make more sense to remote the screen and control from the N900 which has all the personal programs and data you carry around, anyway.

At first the idea seemed to point to using a tablet with WiFi to VNC into the N900, but that would require setting up the N900 as a WiFi hotspot, and if already playing music and possibly using the FM transmitter, that's a lot of power drain even while charging.

So a USB tether from the N900 to a larger dashmount remote touchscreen would seem to make more sense.

It would probably be best if the larger "remote" screen had two pages: one for the remote of the N900 screen, and the other with local functions such as perhaps DVD player, OBD-2 data display, etc.

While I would prefer completely "local hardware" solution in the end, with prepaid 3G and OpenVPN + unionfs, (maybe linuxice or meego IVI) it's possible to make full incar use out of n900 with carman + Bluetooth OBD-II adapter... see http://talk.maemo.org/showthread.php?t=37259

The more I think about it, the more appropriate it seems that there should be methodology to simply & quickly operate your mobile computer from other computers.

I was doing research at a university this weekend, working from a printout of a spreadsheet that had been sent to me. The university had Windows computers that guests could log onto, but of course they had little on them but the original Windows software.

If, by connecting my N900 to the computer via USB, the terminal became a remote interface for the N900, I could have wrapped up all my work then & there using a spreadsheet program on the N900.

Similarly, if in a car, all the maps, music, etc. I need/want will be on my mobile (N900), & there will be no slowdown of learning accommodation for operation if a dash computer was simply a remote VNC-type viewer for my mobile computer.

It would be interesting if something could be devised like the program which some USB flash drives run when you plug them into a computer - they start on the computer a U3 program for file management, device ejection, etc. If, when connecting the N900 via USB to another computer, the N900 could run on that computer a program to operate the N900 VNC-like from the computer, it might be simple & fast.
