We are still working our way up to a proper release. The Lively
Kernel itself seems pretty well ready@this point, as it now runs
reasonably on Firefox, Safari, and Chrome in both SVG and Canvas
variants (at least in the Beta versions that offer Canvas).
It would be nice to be able to add Canvas and SVG variants of Opera
and Internet Explorer.
I believe that Opera only fails due to a few runtime issues and a few
syntax issues that should be fairly easy to clear up. It's a nice
platform in that it supports both Canvas and SVG already, and it runs
on a number of mobile devices.
