Browser Capabilities w/r/t user authentication and forms

Well, I had hoped to get this into an HTML form that you all could help
me keep updated, but that's turning into a bigger hassle than it's

Those of us on the content side are getting antsy to start basing services
on forms and user authentication. Well, more than antsy. As a part of
this I've come up with a table of different browsers and their
capabilities in this respect. Within 6 months I hope this will be a moot
exercise, but for now we need it, particularly those of us who want to
support as many people and platforms as possible.

So, here's the information I've compiled so far regarding browsers and
their capabilities, and which revs of those browser had it solidly
implemented. If I don't know when certain features were implemented, I
simply say "yes" or "no". Please let me know if you can fill in some of
the gaps or have corrections - private email would probably be best, and I
can post the updated table if there's interest.

As an aside, I've been tracking browser usage on my site for a couple of
months now, and over the last week there's been a huge surge in the
number of accesses from clients that don't pass along their name, from
about 5% to 23% of all accesses, and looking at the log doesn't turn up
anything significant, other than most of them come from hosts without
real hostnames, just IP numbers. Hmm.

There's a lot of other odds and ends in my browserlog, but they are
either robots or products under development. This is all I feel
concerned about.
