VLANs are fine. Just remember two things:

1. Each VLAN will need to be defined in sites and services as a subnet and
then joined to the appropriate site.
2. DCs and multiple NICs can be quite tricky. Avoid this if possible
(unless, of course, you know what you're up to then go for it -just check
DNS thoroughly).

Basically we have our network subnetted off with vlans, but use AD for LDAP
authentication on our windows and unix boxen.  We were hoping to trunk the
port the primary and backup domain controllers are on and assign multiple IP
addresses, so the servers do not need to go through the firewall in order to
authenticate to the AD server.
Assuming AD doesn't care, I guess we could test it and see.
