Flashlight mask and cursor tracking

I'm running a psychology experiment and would like to track visual attention to the two halves of the screen. Ideally, I could do this through a browser either in a local file or one posted to the web (I have a couple domains I could use). Javascript, Flash, or something else that I could potentially make updates and changes to (I've got the Adobe Suite) would be ideal.

In general, what I would like is a mask that only reveals a small amount of space around the cursor (a flashlight effect visually similar to that seen here: [url removed, login to view]). I also need the cursor position to be recorded (either posting to a file or saving to the local machine is fine).

Visual Effect:

The mask shown at that website is more a visual representation than it is a template--that one's not really a mask but just changes the background color--a clever trick. I'd like something that could be overlaid on top of, for example, two videos or two images or two columns of text, blocking out everything except the area immediately surrounding the cursor.

Data logging:

The first thing that needs to be logged is a subject number for each person who does the experiment (i.e., a number to be manually entered at the start of the task, which identifies the experimental participant's data).

Then, I need the mouse positions for each subject to be logged in a spreadsheet (e.g., .xls). What I'm more interested in is the half of the screen they were looking at rather than the exact coordinates. Something like "left half" or "right half" should be logged every 100ms or so. This way I can know if they were looking at stuff on the left or right, and for how long.

In the end, what I want in the spreadsheet is the subject number and the proportion of the time spent on the left and right halves of the screen. This way I know if they were looking more at stuff on the left or more at stuff on the right.
