Good. With which kernel(s) have you tested the nnpfs module? SMP?

Will do.

It's not a competition. Some friendly competition is good for the
business, isn't it? ;-)

I don't know for sure, but I have the feeling that some of the leading
names in the kernel development team do not quite understand what this
AFS thing is all about.

The syscall hooking solution is not something that will work forever,
but today the syscall interface is the one that is used by all the
utilities. We are currently working on a /proc alternative but there
are other operating systems which need the developers attention.
Before a /proc solution can be reality in a prodcution environment,
compatible changes must be made in OpenAFS, Arla, Heimdal, MIT-krb,
PAM and maybe more packages.
