Something like XDV/Diazo/Deliverance in Smalltalk?

Hi,

Me and a group of friends in a local hackerspace[1] want to intervene
the interface of this Cynin site using the technologies of Diazo[2],
Xdv[3] or Deliverance[4]. Seeing the way that views are wrote in Seaside
I wondder if there is someway to make a similar intervention/integration
of interface without touching directly the code a la
Diazo/XDV/Deliverance but using Seaside/Zinc or some similar combination.

[4] http://packages.python.org/Deliverance/

Any pointer will be appreciated.

Cheers,

Offray
