Data Limitations?

realistically what kind of limitations should be used with this grid, in your opinion?

Are there limits to how big the javascript array variable can be?

I ask this because in limited testing I seem to be running into some problems (HARD TO DEBUG :-) ) and was wondering of number of rows was an issue.

I could potentially be wanting to store thousands of rows of 200 bytes or so each...

Some guidance would be helpful.

P.S. This project rocks!
