The problem with CH5, is even if they got the browser based version working tomorrow, most of our current projects in the pipeline (and the forseable future) are still going to use Smart Graphics, which means the 2 technologies are not compatible with each other.
So if I have a project with SG touch panels, and the client asks for a web XPanel for additional control (or support personel to access), I can't just convert the existing SG layouts to HTML5 (CH5) like we can with SG XPanels. I would have to re-design from scratch, and is therefore no longer an add-on item, or quick add to a system.
