Afaik it will be committed to the cvs head and thus will make it in 4.7. It uses several things that you will need to backport to 4.6.2:
Internationalization
noquote-patch
service-contract to figure out the local url from an object_id
vuh-page providing stable url for all objects based on their object_id
named objects
Most of those issues still need to be agreed upon (the last three items), but i hope that in one form or the other we will have those things.
To sum it up, yes you will have to do some backporting and even now the package does not completely fit in the current core yet since it depends on extensions not yet agreed.
