[Commotion-discuss] distribution of load among gateways and speed gains?, (Dan Staples)

[Dan Staples]

Upgrading to OLSRd version 2 is something we hope to do in the not too
long future, perhaps within the next 6 months, but I really can't say
for sure. For now, it's a limitation we have to live with.
