(eg. pre-run-time scheduling with constraints) so i can see why it may be easier to start from scratch, and why nasa uses vxworks for its missions, and not one of the sucky linux haxtensions. few months ago, i privately inquired about any real-time work with p9, but noone in the labs knew of any efforts as such. i would be interested to know more... oz -- www.cs.yorku.ca/~oz | if you couldn't find any weirdness, maybe york u. computer science | we'll just have to make some! -- hobbes
