I talked to Laszlo Bacsi over ICQ a while ago about blob events. Last week he came back to me and pointed me to this video: http://www.youtube.com/watch?v=jylEzf01dPE

Guess that answers whether you can couple MPX and FTIR. Here's the email he sent me with more information about what he did:

Hello Peter,


here's how I did the MPX+multitouch stuff:

- I did a standard Ubuntu 7.04 install under Parallels (everything

runs on a Macbook).

- Downloaded all the necessary stuff from the Xorg repository and yours.

- Compiled everything. This was quite easy following the guide on the

MPX webpage plus some common sense.

- Half of my work consisted of solving a video driver problem which

was caused by Parallels. (parallels official driver doesn't work with

the development version of Xorg and the vesa driver had some problems

on bigger resolutions) This is was spesific to Parallels so on a two

machine setup this might not be a problem.

- Our multitouch screen is an FTIR screen (google Jeff Han) and

finger tracking is done by a modified version of recTIVision which

uses the TUIO protocol for sending touch events. I wrote a simple

converter which sends this data to the xf86-input-blob driver in the

required format.

- and that's it basically. the result can be seen on youtube: http://

I don't know if I covered everything, so if there are other questions

I'll be happy to answer them.

Now from what I can tell, the app (CatanTouch) is only using one touchpoint at a time. But since the screen is hooked up through blob events there isn't really a reason why you couldn't use multi-touch as well.
