Then why are you using constraintMorphs? If they're going to have connections 
to them (which are implemented using constraintMorphs), why would you need 
the dynamic re-positioning of the constraintMorph in the connection target as 
well?

Take a look at the Squeakland image to see where Connectors 2 is now (I know, 
I've got to get a 3.8 version out!). I've added support for connection to 
submorphs that have the #wantsConnectionWhenEmbedded property set. So you 
don't have to do anything special to make ports. Just embed submorphs with 
that property. They don't even have to be anything special or have any 
special behavior.
