Yes, you can use ipfw (dummynet) with ipfilter.

Ipfilter has a "count" action that you can put in your rules file which will
keep accounting of the traffic.
Not so sure about measuring via domainname, but you can using something like
count in from any to a.b.c.d port = 80
count out from a.b.c.d to any port = 80
will keep accounting for anything going to/coming from a.b.c.d, port 80.
ipfstat -aio will then show you the accounting statistics gathered. `man 5
ipf` and search for 'count' for more information.
