Web portals work fine, and honestly, it's not like you need to switch 
subnets, either. PPPoE/A implementations work great, as they are already 
designed to utilize radius backends to quickly alter static/dynamic on a 
session. For bridging setups, you have a variety of implementations and 
it becomes messier. Cisco, while maintaining RBE did away with the 
concept of proxy-nd, and didn't provide a mechanism for dynamically 
allocating the prefixes to the unnumbered interface. If you use dslam 
level controls, you'll most likely being using DHCPv6 TA addressing with 
PD on top of it, which works well. Most of which can support quick 
static/dynamic capabilities as it does with v4.
