Right.

You could either put the information in an optional Babel sub-TLV, or in
an optional HNCP TLV.  The allocation rules are similar for both
protocols: either use an experimental TLV number, or document the
extension and get yourself an official TLV number.  (HNCP requires
a proper RFC, while Babel only requires a published specification to be
reviewed by an expert chosen by the IETF, which is much easier.)

I suggest having an implementation first, though.  I'll be happy to help.
