An unnamed source at Microsoft confirms today SSIS 2008 will integrate Silverlight in the next CTP:
The SSIS Debugger with it's stationary tasks and transformations, just sitting there changing color - where's the graphic feedback in that?
The new functionality will reportedly include more "real-world feedback" graphics. For instance, when a Data Flow task fails for some reason, the Data Flow task on the Control Flow will appear to explode. Truncation on loading a destination will cause scissors to fade in near the Destination Adapter. The scissors will then slice off a portion of the Adapter proportionate to the amount of truncation occurring (it will slice off half if you're trying to push a varchar(256) into a varchar(128) column). Unicode-to-nonUnicode errors will cause a brick wall to appear over the data flow pipeline. Success will be denoted by a stick figure jumping up and down with arms raised.
How's that for feedback?!
In addition, the feature is extensible - you can create you own graphics to represent conditional results. I'm looking forward to working with this new feature!
