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.
