Barry Gordon from the CommandFusion Software Google Group has shared a Homeseer plugin that he developed for interfacing with an iPad/iViewer.
It is supplied as a dll for direct placement into the Homeseer root directory. It is documented describing its capabilities and the Javascript code needed to interface to it. The associated Javascript code is supplied in the zip archive as syntax checked Javascript code.
The plugin can be downloaded from Barry's site.
Thank you to Barry Gordon for providing this information and allowing us to share it. Here is the link to Barry's full web site where a lot of things related to Home Theaters and Home Automation are located http://www.the-gordons.net/
