If you have neatly solved the problem of undetectable
route flutter, whereby something distant from your
similarly-numbered machines causes datagrams destined for
those machines to flip among several of them at intervals
(particularly relatively short intervals) then I think
that would be worthy of a talk almost anywhere.
Moreover, if you can generalize the "slick" solution into
moving traffic by choice from one of your similarly-
numbered machines to another (thinking of reboots &
backups, server-driven load balancing and the like)
independent of service (although you could require it to
be a NAT-friendly service, I guess) then that might make a
trip to Phoenix worthwhile.
