we're working on that, for samba-2.

cacheing, to reduce network traffic.  also, nmbd is a single process.  
we'd need to add a non-blocking, state-based way to resolve dns names.  
(gethostbyname() is blocking...)

the DNS administrator.  NOT samba.  and NOT the DHCP server.  samba has 
nothing directly to do with DHCP daemons or named daemons.

i don't care: the samba team deals with patches from different versions 
all the time.  we prefer diff -u, if you can generate it.  patch < 
diff_file usually deals with things automatically, and creates .rej files 
for rejected bits, which have to be added by hand - no problem there.
