We've been running our main domain with the underscore domains delegated 
to AD for well over a decade and it's been neither painful nor fragile, 
at least no more painful than running AD any other way as far as I can 
tell.  We already had a well partitioned and, in some cases, delegated 
DNS structure before Windows 2000/Active Directory came on the scene, 
but we needed to have a single AD thingy (forest? domain?  I can't 
remember the correct terminology).  Replicating all of that under a new 
functional domain didn't seem like a sensible option.
