Updated thorough comparison of Sahi vs. Selenium

THIS IS A VERY OLD COMPARISON AND IS NOT TRUE ANYMORE Click here for the latest: Updated thorough comparison of Sahi vs. Selenium

A brief comparison. Please let me know if any information is incorrect.
Added Watir related data from Chris McMohan's comments:

Comments from Chris McMohan which I have incorporated into this comparison:
Actually, Watir has
a Firefox interface (version 1.0 just released, called "FireWatir")
a Recorder
methods intended for use at the command line like "show_links" so an object spy isn't necessary
Simultaneous playback (via Ruby threads)
Frames support (really excellent frames support)
Popup support native in version 1.5 (coming soon)
Ant support (not sure what you mean, but Ruby can be integrated with CruiseControl)
non-ascii character support (via Ruby)
Learning curve: Watir *is* a DSL for scripting the IE DOM. Ruby is just a bonus. :)
