I agree. As you mentioned, getting rid of CA is a much bigger project, but one that I very much want to do. Things like the dialogs, file upload, and grids (including the complex hierarchical grid in the error log) need to be reproduced with some other technology, which almost certainly requires another 3rd party product.
My goal is to replace CA functionality with jQuery and jQuery UI widgets whenever possible. I am watching with extreme interest the new
jQuery UI Grid being built.
