What IS the problem, exactly? You're describing two things that
doesn't seem to be related: number of NS for a zone, and PTR/DNAME

If you don't "own" an IP address, then usually you don't need to
bother about PTR records at all. If you need to change PTR record for
an IP address that you use (e.g. VPS, colo, home connection, etc) you
usually need to ask your ISP to update/change it.

DNAME creates an alias for one or more subdomains of a domain. Chances
are you won't need it for common uses.

Bonjour should work even without a DNS server.

You could always create your own DNS server if you REALLY need those
record types :)
The cheapest VPS is about $15/year, which should be more than enough
for a secondary DNS server.
