I spoke with Yves Yang today at the Eclipse: Now You Can conference (I think it was a “conference”) in Paris about the eFace product he’s been working on. It appeared on TSS today; you can find the link here. You can find more information here and here. Essentially, eFace is an implementation of XAML that runs on SWT. According to the documentation, Windows Vista, Windows XP, Mac OS and Linux are all supported.
I haven’t had a chance to look at it yet, but it looks pretty interesting.
