That's the point - with @Home a static address IS concurrently in use. You get your cable modem and its up, period. Caveat - I'm discussing 2-way 24x7 @home customers. There are markets where the service is 1-way, I believe, and in THOSE markets, dynamic addressing makes more sense, because they're NOT all up 24x7 (if they are, the Cable-ISP's modem pool is going to get large) >Once concern I have with so many static IPs in use is how do they grow >their network and keep the routes aggregated?

That's one advantage of DHCP vs. static, BUT it isn't a technical issue that ARIN needs to concern itself with in regard to address space allocation, its simply an issue internally as how (not) to piss off your customers.
