They already have if you can run either 6rd or 6to4 and are a Comcast 
customer, even if you didn't happen to know they had.  (Though they do 
plan to turn off the 6rd hack they were using this summer; their native 
trial and 6to4 work well enough to not need yet another transition 
mechanism).

Their kind offer is to extend availability of their 6to4 relays to 
others who aren't even Comcast customers...

(Says this reasonably happy participant in Comcast's IPv6 trial; my 
unhappiness is the state of CPE firmware, not with how well Comcast's 
end of things work; I plan to ditch commercial firmware on my home 
router for OpenWRT momentarily...)
