So WPF/E has a new name.

Silverlight.

Install is under 2MB.

Currently not supporting .NET languages but I'd expect to see that change pretty quickly.

“Silverlight is a cross-browser, cross-platform plug-in for delivering the next generation of media experiences and rich interactive applications (RIAs) for the Web. Silverlight integrates with existing Web applications. Silverlight media capabilities include fast, cost-effective delivery of high-quality audio and video to all major browsers including Mozilla Firefox, Apple Safari, and Windows Internet Explorer running on the Macintosh or on Microsoft Windows. By using Microsoft Expression Studio and Microsoft Visual Studio, designers and developers can collaborate more effectively by using the skills they have today to light up the Web of tomorrow.”

The biggest thing for me in the whole Expression push from Microsoft is in closing the chasm between designers and developers. Yes, there have always been people who sit pretty well in between, but round tripping betwen creative and development types has always been a really hard problem. With WPF I think they've come pretty close to cracking this nut.

I'll be sure to be posting more on this Live From Mix in a couple of weeks.... I'm gonna try and use my time at Mix to get back into bloging
