Okay, sounds good.  Thanks, Russ; I'm pretty lucky to be able to learn
from your experiences.  This is the sort of thing that I would've
blindly plunged into (in the name of elegance) without your advice.

So, to summarize, I guess the basic problem is that a lot of
"applications" (ie things that use libkrb, such as AFS) assume that to
get the realm of a host, you take its hostname, truncate some leading
portion, and capitalize what's left.  Instead of this, those apps
ought to be letting libkrb figure this out (which it will do using DNS
entries, thereby using the capitalization of the DNS TXT record, which
can be assumed to be correct).  But there are too many apps out there
that don't do this, so it's going to be painful to break this
assumption anytime in the forseeable future.

Does that sound right?
