The main problem I have with this registry idea is that there is already a facility in the kernel for this type of work. It may not be perfect, but it works and may be considered ``standard'' in the BSD world. Another problem is that of robustness: if the registry get corrupt your whole system is compromised, see your average Windows 95/NT system. It's something like putting all your eggs in one basket and then sitting on it... Hans BTW. I do like the ppbus driver, it solves quite a few problems, thanks. -- H.
