I am less than enthusiastic about most of the desktop java
applications I use.  They are, for the most part, sluggish, memory
gobbling beasts, prone to disintegration if I look at them cross-eyed
or click the mouse too frequently.

Usability problems with java applications are not necessarily due to
managed code, of course, but the idea of creating a full-featured
browser, from scratch, with usability as good as IE and Firefox
strikes me as a fairly tricky project.  What about using the
facilities already provided by the OS to enforce the sandbox?  Rather
than scrapping the existing codebases, start running them with
restricted rights.  Use mandatory access control systems to make sure
the browser doesn't overstep its bounds.

Brian
