The fact Mozillas XHTML implementation is too poor to be used, and
IE's XBL engine is absent and ... are all problems with UAs meaning
authors have to be hobbled with Web Forms 2.0 rather than good
replacements grounded in well specified technology unlike HTML.

The whole rationale of Web Forms 2.0 seems to me based on overcoming
UA problems in legacy specificatios.

More likely sent direct, the 4 megapixel camera in my cell phone
delivering images to other cell phones is not useful to use the full 4
megapixels, neither is it useful to the user to upload hundreds of
megabytes for it.  Of course at the same time publishing to the web
may well usefully want the 4 megapixels uploaded.

The reason why server sampling is not a good idea, is that the user
experience of uploading huge files is not something they enjoy.

I really don't understand how a company who I understand makes most of
its income in an environment where bandwidth is so expensive are
happily suggesting the "bigger the better" approach.
