Nope -- the express intention was that it could be used for basic IP 
connectivity, for mobile devices. In OLSR, every node is a potential IP 
forwarder unless it explicitly advertises itself as being unwilling to 
forward.

Applying routing policy gets more important at the border. The OLSR 
implementation in XORP is intended to give people a means of 
connectivity between MANET and non-MANET routing domains, by 
redistributing routes into the OLSR cloud.

I daresay these capabilities will get more important, and relevant, to 
the MANET picture as time goes on, but it's best to leave them out of 
the operational picture for now, in my opinion.
