D2W is an amazing technology and we may, some day, discover how to make 
the way inference rule engines work more understandable.

I banged my head against just this issue a while back. I had a Docklet 
(if you can remember what the heck that is) that would let you drop an 
eomodeld onto it, and it would generate and launch a D2W app for that 
model. I wanted to, with a running app, drop another eomodeld onto the 
(java) app icon and have it do the right thing. Aside from the Dock 
things, getting the dynamic loading to work reliably was not easy and 
was not getting easier as I learned more.

I think that if a D2W app could dynamically load additional models, it 
would be more compelling, perhaps doing a better job of being a data 
admin interface. But I might juts be too weird. Who knows.

cheers - ray
