BIND 8 with DYNUPDATE capabilities

[Wilde, Jeff]

I know that windows 2000's dns it is integrated into the active directory so
that you can basically have two primary name servers and replications is
always taking place because of the AD.  If one name server fails, the other
name server will automaticaly keep on receiving dynamic updates and the
replications will take place once the failed server comes back into service.
I currently have bind 8 set up as a master/slave configuration.  If my
master was to fail, the dynamic updates wouldn't be handled by my slave the
way I have it configured.  Is there a way to have either

a) two primary servers that replicate zones to each other
b) have master/slave setup with the higher soa value being replicated to the
other server.

My other question is, is there a timeout on the dynamic updates to cancel
old stale data?

Thank you in advance
