If the user is smart, it's not very hard for him to convince pretty much any
DHCP server to give him a new IP every few minutes, especially with PPPoE
based services (such as 90% of DSL) - just bring down then up your PPPoE
link, bam, new IP.
FreenetSpeeder-1.0 will automatically do this for the user, of course (think
kazaa lite's "auto-more sources needed" feature :-p), meaning that the user
won't even need to be smart.
