[Voyage-linux] Mesh Networking

[Punky Tse]

I see that meshnode (http://www.meshnode.org/downloads/deb-pkgs/) has 
the latest version 0.4.10.  But if there are source deb, I can build and 
put to voyage apt repository as well.

Andrew, what is your experience about frottle?

Keegan, I know you have been asking olsrd 0.4.10 in official debian 
repository.  May I know the current status about it?  Otherwise, we may 
consider uploading the package by ourself.  I also have frottle package 
in voyage repository for uploading too.  I know one debian developer, 
who is participating wireless community in Greece may help us in the 
process.
