There's no option for Safari
On WM I'm still using straight PIE (lost the tabbed add on a few rebuilds/devices ago), I've dabbled in the others but not really found one I liked enough yet. I tried to load Skyfire this week and just got an error so at some point I'll need to investigate a bit deeper.
Is there anything that does flash website rendering on the client? I have a possible use for this in the enterprise.
