We have a client that uses Coldfusion and we are pitching Zope to them for its workflow strengths.  Here is what I think I know about Coldfusion:  its java-based? and has a J2EE server. Am I correct.
 
They might want to use coldfusion to continue to develop their content but would be amenable to a Zope server.  Does anyone have any thoughts or experience here.
 
thanks in advance
