[c-nsp] BFD and IPv6 on 6500?

Hi,

is there any lore whether support for "BFD + IPv6 routing" is on the
roadmap for 6500 / IOS 12.2SX?

Feature navigator claims SRE and 15.1T have BFD for IPv6, and 
12.2XNE (wtf?!) has support for BFD for IPv6 static routes, but that's 
all not overly helpful for us - 6500, Sup720-10G, OSPFv3 for IPv6...

(NB: what about BFD for ISIS - how will that behave in a dual-stack
environment?  The feature is called "IS-IS support for BFD over IPv4",
but I assume that an IPv4-BFD-triggered outage will kill the whole
IS-IS adjacency, thus taking down IPv4 and IPv6 forwarding on that 
link.  This *might* be a reason to change IPv6 IGP to ISIS...)
