If company A has windows AD/EXchange 2000 in and company B has Windows
AD/Exchange 2003 and they are both in a single domain/forest mode. What
is the best way they can start trusting each other?

To my understanding to create a forest trust they both must be Win2k3
or I my wrong?

The objective is that the administrators of each company A/B would be
able to interact but in the mean time and manange their infrastructure
but then be able to separate in the future.

We would like to maintain both Exchange servers separate but at the
same time share reasources like the address list, public folders etc.

What do you think?

GALSync in MIIS Feature Pack to synchronize GALs (can be scripted, but
painful and one-time dump, not a true synch like MIIS)
Rod Fournier has step-by-step instructions on his blog

InterOrg Replication Tool to be able to see free/busy (and replicate other
public folders if required).

Will require trusts to be established. You can create a one-way trust (each
way) between 2 Windows 2000/2003 Forests.
