Why not just configure 25 secondary IPs on a single box? -C
Avoid *any* technology that makes more efficient use of my address space. Then I'd generate additional redundant services (legitimate and opertional, just not used much) to fatten up the foot-print. About 25 Linux boxen, implemented on BookPCs, ought to do the trick for a /19. Personally, I have yet to be pushed to such a solution, but I've thought about it and I'm not the only one. If the rules are set such that I have to do something like that, or fold the company, I would do it in a heart-beat. There is a limit to what I will sacrifice on the alter of "community spirit".
