The Thin Website

I’ve been writing server side heavy code for several years now. I need to expand my client side skills. I’m nooding this idea:

Static HTML + JQuery + CSS + JQuery plugins for the common components (drop downs, grids, etc)
ASP.NET website with *only* WCF or WebService calls that *only* talk to a SQLite database (and maybe a few C# library methods that the client can’t be trusted to run, such as discount calculations, etc)

Except for the webservices, this website would be fully standards based.

I mulling over what might be an even lighter middle tier, but haven’t thought of one yet, maybe astoria.
