you are completely correct that you will need a second DAS - and, IMHO,
for good reason:
A domain combines/groups a set of GF installations (i.e. standalone
managed servers and clusters) for a particular environment (a.k.a.
"domain"), such as (in its broadest definition), your production domain,
integration testing domain, unit testing and development domain - or
even smaller (sub)domains for particular (subsets of your) applications.
Hope this helps & best regards,
Andreas
