First, a short note: You can't calibrate the pen (yet), so i turn the iliad 180° to get the best match between pen tip and appearing point. But i think this will be fixed. So no one really used it yet.
1. At the moment you can draw on these obscure xeb files and images. If you draw on an image, a copy with the changes will be saved and a file with the x and y coordinates of your strokes is created.
The quality of the created image is not really great, but it looks quite nice if you throw your stroke data on your favourite plot program and use some kind spline instead of straight lines.
2. no idea. It's not announced yet, and they are focusing on business needs (tm). But there's no reason why it shouldn't (in the stroke data is a thrid line filled with zeroes at the moment, i assume it will be used for pressure in the future)
3. nope, no estimates. i would guess release of a proper SDK+3 month for enhanced functionality of the iliad.

5. We'll see. I assume that they should try not to fsck up Iliad v1 if the want to be able to create an Iliad v2. Anyway, color eInk is still some way to go, but the fujitsu-siemens (?) prototype looked promising. I would bet on 2008 for color. (or 10-15 years later, as usual, if ereading doesn't take off this time)
That's everything i know about notetaking. I hope it helps.
