Ken,
>1 - HTML/Web is attractive but I don't see it giving me the visual appeal or speed I need - with grids, etc.
This is the direction I went for Mac -- a Web Connection app that I was already building for PC users. With IE5Mac due out "early 2000", it will handle HTML 4, CSS 1, DOM 1, XML.
>3- it must be stable and distributable as part of my Vertical App
Have you considered your normal VFP app running under Citrix for the Mac users?
