With Great Difficulty (tm). As far as I know, the only way of deploying native 
code over the web is ActiveX, and I don't know if you want to go there.

As for applications in JavaScript, DHTML (give or take AJAX, depends on what 
you really need) is your best bet for this. Expect bugs, and know the content 
of quirksmode.org by heart if you plan on supporting IE6 properly for the 
more advanced (read: flashy) things.

As for the SVG plugin, I think it's something all the users of your 
application will have to install in their browsers. I admit I'm slightly 
guessing here, because I don't have much actual experience with SVG on either 
side, consumer or author. As for over-the-net drawing, I think you're once 
again looking at AJAX, unless you know you can neglect the browser reloads 
and the gruesome amounts of overhead downloading an SVG image over and over 
again involves.

As for question 3, it's a bit too generic for me to be able to answer.
