Yes, you can register whatever RR makes you happy. Just write a small
Avahi client and register an additionaö A or CNAME RR for your
machine. It's not black magic.

If you complain about the docs, than please remember that this
software written by volunteers and it is given to you for free. So,
instead of complaining, how about reading the sources and contributing
better docs? Also, the Avahi web site is a Wiki and can be edited
freely.

Yes, since that registers both a A and a PTR RR. In the latter will
conflict with the main host name of your machine. If you want to
register just an alias, then you want to register only an A or CNAME
RR. (see above)

If you just want to define aliases via a static file read by the Avahi
server, then you're welcome to send a patch for this!
