yes this is indeed one of the best features of SVG.  i've personally 
experimented a lot along those lines,
and i've allready written a simple clock that could be parametrized.
i would suggest using xslt for that purpose, here is how i think the 
whole system could work:

-have a html page with some form elements.( theis could be created 
dynamicly, based on the object templates)
-create an xml serialisation of the object you want to create with the 
values from the input fields as parameters.
  a clock could look something like this:

  <clock hour="12" minute="32" second="17" r="20" />

-send this xml to the server, perform the xslTransformation, and send 
the result to the client.
 we could then ship object template files and the xslt stylesheets with 
the packages, so
 a user could create svgs from that templates without connecting to the 
server.
  
the question is if there is a gui needed on the client side, to do the 
transformation,
or if its simple enough , to edit the object files, and perform the 
transformation on the commandline.
i think the latter should do fine...

if this is the way to go, we might need to ship an xslt processor.

these are just some ideas, what do you think ?

here are some of my experiments:
