Markus has finished a first patch for the problem, it just need a little bit 
cleanup and window dressing... (oh my god, we just talked about it a day or 
two ago ;) )

our plan at the moment is to enhance the new "RouterId" config parameter.

1. option:   "RouterId   <Main-IP>"

this option will set a fixed router id AND will set the source of each 
interface to the main-ip. To prevent an error (which can happen if no 
interface have the src-ip as it's real IP) we plan to create a "pseudo 
interface" lo:1 which will have this IP as long as OLSR is running.

2. option:   "RouterId   <Main-IP> internal-only"

this option will set a fixed router id, but will not change the source IP of 
the routing tables. Maybe good for experimentation. We hope you know what you 
are doing. ;)

I think the patch for this will enter the development tree soon, maybe even 
this weekend !
