Hi,
You could write a script to be triggered when the originating object
changes state. 
In this script you could execute the transition you want on the second
object, like its done in content_status_modify.

Check http://www.zope.org/Members/hathawsh/DCWorkflow_docs
for info about writing a script to be triggered by a transition.

Hope this helps you,

Sune B. Woller
