I know about bat-hosts, but this only works when the host displaying the
data knows all the MAC address/hostname mappings. For community meshs
like Freifunk networks it would be much nicer to allow each host to
supply its own hostname for vis in my opinion. I think one possibility
to add this without breaking compatiblity would be adding a hostname
record after the neighbor entries in the vis packets.

It would be nice to convert the reserved field in the vis packet
stucture to a flags field for things like this, but AFAICS the current
code never sets this to zero, but this is a byte of uninitialized memory
that is sent over the network - but again, I might be overlooking things
as I'm not yet familar with the code.
