Re: [regrep] Dynamic Discovery/Binding/Invocation

Joe,

The ultimate panacea - instant computing.

First we have to get everyone using CAM templates. ; -)

Then - you really do have the possibility that agent
directed configuration can occur - since you can
create CAM templates for all your EDI and SQL
information sources as well.

As you note - we spend 2004/5 getting it so that
humans can do it and get it working.

Then 2006/7 we get a huge research grant and
use it to enable agents to do it.

One caveat - someone has to create the BPSS
with goals and process steps first - the agents
cannot just invent everything!!

DW.
