Yep, we have received quite a few requests to transport arbitrary informati=
on
(node gps position, host name, neighbor information, client station list,=
=20
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 serv=
ers
and request from then.

This software is called A.L.F.R.E.D (Almighty Lightweight Fact Remote Excha=
nge Daemon),
and it's still in the middle of development[1] and will not be usable for p=
roductive
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
