Kevin,
>Let's use this thread to see where developers are most interested in having a "TI" layer...Paul has already mentioned a few places...I'd like to have a broader picture of what developers are interested in before I implement anything (sounds suspiciously like a use case < s >).

Good idea,

We would be glad to see ILayer at the following places:

cBaseForm
  iLayer
    cBizObjForm

cBaseForm
  iLayer
    cBaseModalForm

and 

VFP Controls
  iLayer
    cContrls

That would be on my wish list and would help me out in most cases I can think of.

Regards
Marcus
