Might be a better question for the SP forum, as it primarily deals with NAT for VRFs. 12.3(14)T is probably a bit newer than you would even see in the SP lab.

I see what you mean about the documentation.

I tried a simple example with a static source ip mapping an internal vrf ip address to a global ip address. The natting seemed to work fine when I pinged from inside the vrf to an external global (non-vrf) ip address. I just didn't see any return mapping. If that were to work I could see a nice way to communicate with static vrf routes between the global routing table and a vrf.

I would be curious to get this working and to hear about any progress you are making.
