If you make an ajax call for each form field, then you
need to code individual field checks on the server
side, and you still want/need the ability to check a
form in one call.  This has a tendency to violate the
DRY priciple.

I like the
individual-client-side/whole-form-on-the-server model.
So that's my two cents anyway.


Speaking of DRY, do we have an equally quaint
retrofitted wording for the opposite TLA - WET?
