That's probably a good idea.

It does actually, starting with the 2.6 kernel a large chunk of the uClinux 
project was integrated into the mainstream kernel.

Well, a couple years ago, maybe not.
But that's changing, and Linux is leading the pack.
This is exactly where I'm coming from and what I'm researching right now.
MMUless microcontrollers like ARM's and Coldfires can now run the mainstream 
Linux 2.6 kernel, or a uClinux patched 2.4 kernel.
These kernels can run alongside uClibc, busybox, MTD and somescaled down 
initialization scripts to create a full blown OS(the uClinux distribution). 
RTAI and the new RT-preempt patch provide real-time control capablities, 
without sacrificing the features of a standard OS, and do so while 
maintaining an open source approach without patent worries.

If you can't make a point without insults, maybe you should take a break and 
think about whether it's really a valid point.

Not really, Adeos basically removed the oldschool proprietary approach that 
RT/Linux relies on and can be used without patching the Linux kernel, but I 
agree, we are quickly moving off track, this is an thread for 
rtai.org/vxworks lists
