There are facilities for the media plugin to track mouse and keyboard 
input. I suspect they are based on the same internal viewer functions 
that send data to the touch functions in LSL. Getting them to work with 
the media plugin may be reasonably easy. The trick would be letting 
everyone else in a sim see them. Using LSL touch functions you can rez 
temp prims at various positions along the surface of the prim you are 
drawing on. The drawback is that it may take hundreds, or even a 
thousand or so prims to make a complicated drawing and much of it will 
be gone within a few seconds that you finish the drawing if not before, 
but at least everyone else can see them.

An alternative method is to use a drawing app displayed on a webpage and 
let the user draw on the webpage. This requires the webkit media plugin 
to work and I'm not sure how reliable it is yet but everyone watching 
the webpage could see what is being drawn.

Other alternatives would be some kind of VNC on a prim ala Aimee's 
Recursive Life demo. That goes back to the question of how to display 
the image for everyone else to see.

My own [proposed] solution is to do some kind of VNC thing via a 
mediaplugin so that the lecturer/artist can have realtime control of 
what is drawing, and then rebroadcast it via streaming media. This would 
cause about a 10 second lag for the audience from what I have seen and 
from talking to people who use media streaming for lectures.

There are no doubt more complicated and interesting strategies 
available. I'm hoping to get rendering from squeak smalltalk to media 
plugin working locally reasonably soon now. Getting it to the point 
where others can see it will be a lot more work, I suspect.

I've got a few diagrams and examples of what people have already 
done/are trying to do listed on a wiki page:
