Agreed.  It's an ideal place for many of the things that are in proc, and many 
things we'd want to add in the future.

You could possibly abuse sysfs into supporting ioctl but I'm pretty sure the 
kernel people would find that quite distressing ;-)  I had the impression 
binary files under sysfs were also a no-no (all meant to be cat-able - 
addressing one of the other problems of /proc), but I could be mistaken.

Cheers,
Mark
