WPF/E will support Safari and Opera as well as IE, Firefox and Netscape browsers (all via plug-ins).  We'll support Windows 2K and above as well as Mac OS X 10.4 and above.  For IE, we use ActiveX and for other browsers we're using Netscape plug-ins.  Konqueror is not currently part of our Windows/Mac test matrix but should work with our Netscape plug-in.

We are working on a plan to support Linux platforms and appropriate browsers but Linux support will be post our V1 release (V1 is ~1st half of 2007).
