Thanks! :)

I am just as much interested in core kernel dev. It actually might be  
easier than to follow some HW specification.

I'm trying to say I can cope with following spec. and probably could  
develop a driver. But is there anything in the core kernel that might need  

Also, is there something (other than support) that makes vxWorks more  
preferable to space industry than RTEMS?

I'm guessing about 10 hours/week for for about 6 months, but that may vary  
a lot. I still have some school to attend to and other work, though.

Chris is subscribed to this ML so he can reply now. Or should I address  
him directly?

That was actually the least preferred. :)

For testing I'd need the actual hardware, wouldn't I?

I am fluent in C and C++, understand the main data structures and  
asymptotic time complexity, have experience with code optimalization,  
multithreading, recently I implemented basic mutexes for school course,  
have done my bachelor thesis on MBR and GPT manupulation in HelenOS (see I'm also playing with Aria G25 from Acme Systems, Arduino  
Pro mini and have my own Raspberry Pi. I likely  forgot something, so feel  
free to ask specifically. Please also note I've never done any work inside  
kernel before - but that doesn't stop me! :)

Again, any more input will be greatly appreciated! Just come at me and  
tell me what you'd like have implemented or reworked and I shall look into  
it! :)
