Yes and no.  Technically that will work, however, dynamic DNS does not
offer the same information as WINS does currently in a Samba
implementation.  Since Samba is not emulating an AD domain controller,
but an NT4 domain controller, the workstations are expecting certain
information to be returned about machines (the various flags after the
names you see in WINS) as far as their capabilities are concerned.  This
is offered in WINS (also in DNS, through the use of SRV records, but
Samba does not generate these currently and I don't know how the
workstations would interact, finding the entries it would expect an AD
controller to use in DNS and then finding an NT4 domain controller
there).  If you're all on the same subnet, this is not a problem because
it can find the same information through broadcast resolution, but who's
all on the same subnet these days? :)  

The Samba3 HOWTO covers this very well under name resolution.
