A lot of my visitors are blind (with it being a site for the blind), and often when trying to diagnose problems, I'd like to know what version of browser etc they're using, whether flash is installed. Because more often than not, someone will swear they are using X, when in fact Y is installed. Currently, I'm using http://jsbrwsniff.sourceforge.net/usage.html piped into an email, but I've got 2 problems here:
First of all, jsbrwsniff is quite "heavy" and hasn't been updated since early 2007, so there's a lot of -1's in the result.
Secondly, if I call it as follows, the page reloads:
<a href="#" onclick="sendEmail()">Email feedback</a>
And if I call it like this, the page goes blank and looks like it's trying to infinitely load a blank page:
<a href="javascript:sendEmail()">Email feedback</a>
See the nightmare for yourself here:

Now, I know there are 1001 articles and comments here and elsewhere saying "don't use browser sniffers, they can be spoofed (etc)", but honestly, you'll have to trust me that this is a significantly useful tool when you're talking someone in their more "senior years" and using a screenreader through "help about", when they've clicked the wrong window to start with!
I'm using jquery anyway in the site, and I'm aware of $jQuery.browser and $jQuery.support, but these don't tell me the elements I need (like whether Flash is installed, and what version etc). I've looked everywhere for a jquery plugin for my needs, with no luck.
Finally, if I have to stick to the current method of jsbrwsniff then it's not the end of the world, but if anyone knows a way of launching the user's email client populated with the information I need but WITHOUT refreshing or blanking the page, I'd love to know.
BTW - there's a good reason for not using a webform, which is simply because it's easier for the screen-reader user to use an email client they are used to.
Thanks!
