I agree, Nathan.  That's why I designed the revitalization process.  The
idea is simple:

1. Decouple the business logic and the user interface
2. Redesign the user interface using the existing business logic
3. Redesign the business logic

It's simple, fast and flexible.  You may never have to go beyond step two
for many of your programs, which is as far as the 5250-bound solutions go.
But for those that need to be redeployed as true client/server applications,
you can then go to the next step.

The next step is going to be to design a language that defines business
applications.  I think the folks who are basing the concept only on
transactions (such as XAML) are missing the boat.  The idea is to be able to
define at a macro level the entire application process.  With this approach,
you can first define your existing legacy applications, then include them in
an overall business process.  Once you've done that, you can then rewrite
pieces and insert them into the overall application flow.

Revitalization will do that quite well.
