Rather than use _workstation for this you'd probably be better off  
registering your own service.  This way you can pass on states (like  
online/away/etc) and other useful info .. plus you won't see users  
that aren't actually running your mesh software.

'avahi-publish' itself can be killed .. there is in no way a require  
to restart avahi-daemon.

to do this properly you would have to integrate support with VLC to  
publish/unpublish within VLC when it starts/stops - using /etc/avahi/ 
services/ or avahi-publish is a workaround to not having this  
available - but obviously not as nice in that it won't register/ 
unregister with the actual program.

Thanks,
Trent
