In the technical report there is some fairly straight description on how to 
implement it:
http://www.cse.yorku.ca/course_archive/2006-07/F/6590/Papers/yang2.pdf
(page 9 and 10).

I think you would need quite a few changes to olsrd in incorporate MIC. 
* 1st you have to have ETT
* Then you need your own routing table for each incoming interfaces (I think 
only linux support this)
* TC messages must include all links of a node (atm, they only include the 
best link to a neighbor afaik)
* You must construct an isotonic (virtual) network tree from the non-isotonic 
real one; and calculate SPF for each interface you have.

Just from memory, there a few minor things more. This means imho, that the 
metric would not just be pluggable but require quite a few changes to the 
core. But it is feasable ;-)
