By default all domains within a forest have a hierarchical and transitive
trust with one another.  So it doesn't matter where the clients and users
reside.  So my guess is who helped design this layout is still thinking in
terms of NT4.  If you are doing this for security reasons then this isn't
correct, the security boundary is the forest not the domain, because of this
I would strongly suggest that you reconsider and create a a single domain
within your forest.

The forest structure you describe will require a minimum of 6 domain
controllers, to be properly protected in the event of any problems, if it
were a single domain it would then be only 2.

Ulf B Simon-Weidner has a short explanation on security boundaries that you
might want to read over:
