DHCPv6-PD (prefix delegation) with the relay installing static routes is probably the most straightforward way.
Apparently that has it's own problems right now actually: http://blog.ioshints.info/2010/10/dhcpv6-relaying-another-trouble-spot.html
Letting home CPE participate in routing does indeed seem like bad idea; I haven't heard that seriously suggested before.
I guess "Comcast Business Class" cable service isn't necessarily considered home service, but I wouldn't call it a dedicated bandwidth contract either. The CPE that they use (SMCD3G or similar) actually does this for v4, that is if you purchase a "Static IP Block" from them, they actually use RIPv2 to send your prefix (usually a /27 or longer) to the headend. Obviously authentication is used and the CPE firmware prevents the end user from tampering with any part of the RIP configuration, but the point is that RIP actually is used at a large scale for this purpose. -Bill
