Urk!  I don't mean to be insulting, but the notion that you would roll
_any_ solution out for a problem of this size based on word of mouth freaks
the crap out of me.  If you have a genuine need for 500Gig of news spool,
and enough users that mmap'ed I/O in nntp is needed and the number of file
descriptors is going to be a problem, and you're willing to change
architectures if need be, then if you don't have tools - I'd suggest you
write some!

[And better to start early, because once you roll into production it's too
late to write the tools :-),]
