Feature request: UDLR

It would be great to have support for UDLR protocol which is described in RFC 3077.
As I can see the only platform supporting UDLR is Cisco. It would be great to have UDLR support in Mikrotik!

I am going to use RouterBOARD in production as a router for wireless streaming with straight and backward channel. Both channels are different interfaces and they are unidirectional (UDL). The main cause to have UDLR support is multicast traffic streaming over UDL.

Here is Cisco variant of UDLR support:

Could any of developers see the RFC to tell how difficult it would be to implement such a feature?
Thanks in advance!
