Yep, we have received quite a few requests to transport arbitrary information
(node gps position, host name, neighbor information, client station list, 
the weather forecast, etc ...). Actually we don't want that in batman-adv
to not bloat the kernel code, so we are currently in the process
to implement a userspace daemon to allow broadcasting this kind of data - in
a clever way, that is collect information on one (or a few) designated servers
and request from then.

This software is called A.L.F.R.E.D (Almighty Lightweight Fact Remote Exchange Daemon),
and it's still in the middle of development[1] and will not be usable for productive
use right now. As soon as it is finished, we will move the vis server to it, and it
will be possible to use for custom purposes (like your tx-power/rx-gain/... info).

I'd like to ask for a little bit more patience, we will announce a release as soon
as we consider it usable. :)

Thanks,
	Simon
