DVTI, SVTI and routing protocols

Apparently dynamic routing will be supported with DVTI Cisco is in process of changing documentation to reflect this.

After several days of bugging Cisco SEs and TAC I finally got a clear answer on several questions I had regarding DVTI,SVTI and routing protocols.

It is true that you CAN run routing protocols over DVTI tunnels - however that is NOT recommended OR supported - because it was not tested.

Also according to Cisco SVTI and terminate on DVTI, but again routing protocols is not supported in this case, static routing should be fine though.

I'd like to stress out we're talking about Cisco support for those techs, it still might work but good luck getting support from TAC/SEs.
To quote rfc 1925, section 2 point 3:
(3)  With sufficient thrust, pigs fly just fine. However, this is
        not necessarily a good idea. It is hard to be sure where they
        are going to land, and it could be dangerous sitting under them
        as they fly overhead
