some mails get lost in this stream, so just keep bothering us until you have 
your answers. :)

Yes, there is such a functionality. The online manpage shows the version of 
the trunk.

It requires each gateway to have a DHCP server running. The clients will 
select their gateway and relay the dhcp requests via unicast to the selected 
gateway only.
You only need to activate the gateway / client mode and have a dhcp server 
running. 


> **If so why do you mix Layer 2 and Layer 3 now?

If you don't want to mix layer2 / layer3 then just don't use this feature. It 
is disabled per default.
If you have a better idea how to handle multiple gateways in a layer2 mesh we 
are very open to your suggestions. :)


> **When do you think this function will be in the stable release?

Unfortunately, we did not get around finishing it to the point that we feel 
comfortable with releasing this feature. I think the trunk is quite stable but 
still lacks some things. E.g. blacklisting / whitelisting gateways, IPv6, etc.
