I build FreeBSD based flash images for my accespoints (NANOBSD),

These images get thier hostnames at boottime and register themselves in

It is more work but gives full control over ip, and daemons.

On the ap's it run:
- snmpd
- sshd
- named (if needed)
- sflowd (sflow information)
- puppetd

If want more details about this setup:

So your options it choose option 3
