Hello, great to hear from you.

Yes I did that, but haven't had time to try it out yet.

We also use a RTAI + Scicos + Comedi combination for your projects but for new 
projects we are looking for more up to date solutions, preferably with the 
same comfort RTAI / RTAI Lab and xrtailab / qrtailab offers.

Sure.

As I said we  mainly use  RTAI + RTAI Lab + Scicos (Scilab 4.1.2) for 
experiments where higher update frequencies are required  or where jitter  is 
not acceptable.
Examples are:

Teaching
 * Inverted Pendulum

 * Magnetic Levitation

Research
 * Active Vibration Control

  * Various FES (Functional Electrical Stimulation) based  projects

berlin.de/Controlled_Functional_Electric_Stimulation_for_Rehabilitation_Purposes

We use the HART Toolbox (hart.sf.net) and own C/C++ functions to interface 
with various external devices (mostly USB / FTDI) (Linux Kernel driver based).

We appreciate the rapid prototyping with Scicos and the ability to change the 
variouse block parameters on the fly with xrtailab / qrtailab. (RTnet based 
interface to RTAILAB).

However we like to be able to use Scilab 5 and newer kernel versions.
We also would love the possibility to cross compile your Scicos based code for 
lets say the the beagle bone and control  this software from another PC.

This should be possible, as long as the result is Open Source and we can 
modify the code to our needs.
