[OpenAFS] Two windows client questions

[Tom Ed White]

Question number one:

Windows client AFS versions are running behind Unix fileserver AFS
versions. Is it okay to have a mismatch, ie UNC's 1.2.6 windows client
accessing a 1.2.7 Linux fileserver?
Question number two:

I've been playing around with Rose-Hulman's WAKE frontend for managing
logins and AFS/Kerberos 5 compatibility on Windows clients. To me, it
seems pretty slick, especially if you're forced to use a W2K DC as a KDC.
Any caveats with this app? Any recommended alternatives?
Thanks,
