EzVPN and NAT Traversal

Can EzVPN Phase 2, as implemented in IOS support NAT traversal (or any method of encapsulating the encrypted packets in either TCP or UDP)?

I would like the ability to use an ADSL router (e.g. 837 or equivalent 1700-series) to act like a VPN 3002 in Network Extension mode, and it's possible that the IPSec packets may need to be encapsulated. The advantage of EzVPN over a traditional LAN-to-LAN setuo is that it should work with a dynamic IP address on the ADSL router. The router would be dialling into a VPN 3015 Concentrator.

I don't think that this is possible
