Yes, it probably would be ;-)

Are we talking Unix clients here and if so what OS ?

The main problem that I see is that, whilst you can (probably) easily
get the dhcp server to issue a dynamic ip then use 'on commit' to run
a script to change this to the next available fixed IP, you would
have to issue a release then ask for a new IP (which should get you
the fixed IP) or reboot.

You could probably wrap the 'net ads join' in a script to do this,
but, again, I have never tried this.
