Jesus, you sound like the X11 fanatics I used to debate with about NeWS, long before anyone had envisioned Google Maps or coined the term AJAX for what we'd been doing with PostScript since the 1980's.

The NeWS window system was like AJAX, but with: 1) PostScript code instead of JavaScript code 2) PostScript graphics instead of DHTML graphics, and 3) PostScript data instead of XML data.

Computers and networks are fast enough (especially now 35 years later) that it's ok to perform input validation twice, once in the front-end to make the user experience tolerably fast, and again in the back-end to prevent fraud. This is not rocket science, nor a new idea! It also helps if the client and server are implemented in the same language (i.e. JavaScript today), so you can use the exact same code and data for modeling and validation on both ends.
