I wrote a javascript library to use an html table as a database.

This is only useful in comparison to other solutions if you actually want to display the data as an html table.

Have you seen the Array methods in JS 1.6?

Granted, that's Firefox 3 only, but they could be precisely emulated with a library. IMO, attaching methods to Array is more the way to go here.

Hey there, guy. So you bought yourself a shiny new Core 2 Duo/Quad machine. Good, you're gonna need it, cause your web browser is about to get even slower thanks to Taffy!

The intention isn't replace a server database but instead manage more efficiently the information you'll store in Javascript variables anyway.

Many Javascript-intense webapps could use it.

Used correctly, this could speed up some web apps by helping them to avoid ajax calls back to the server.
