Anti-aliasing and brushing algorithm for Tablet LCD Monitor

I have a problem to implement drawing  programs upon the tablet LCD monitor with pen. I need free-drawing program working as well-known softwares such as Free Notes, Office Ink, or Art Dabbler.

The Tablet LCD Monitor can be used instead of tablet PC without mobility. It will provide much less expensive and wider screen.
The pen detects the presure upto 1024 levels. Thus, it will work like brush depending on the pressure when your are moving the pen.

I am looking for a free drawing algorithm with/without pressure of pen. Faster routine will be preferable since it should work in real time.

I'll appreciate it very much.

Thanks for Comment from g0rath.
His answer is right if the operating system is one of TabletPC, Windows 2000, Windows XP.
But I want it to run on MS Window 98 and all other MS desktop OSs over Window 98.

Please send me comments.

Thanks for your continuous reply.
There are tablet LCD products functioning  as a LCD monitor as well as touch panel.
When you write on the glass surface of LCD monitor, the inking data is drawn on the LCD panel. When I replace my old Monitor with this tablet LCD monitor, it works like tablet PC. I use the main body of PC as is.
This configuration is much less expensive solution. I'd like to use it for e-learning project. Wacon is selling this product for 21" but it is very expensive. There are less expensive Taiwanese products.
Anyway, I'd like to run it on Window 98 and other MS OS since many people have different environments.

Ah I see...

$1899 for the 15"
$3500 for the 18"

And these are not "digital ink", since that is propiertary technology owned by microsoft and only in their sdk. These other groups have their own drivers to have the pen act like a mouse, and only in specific applications use the sensitivity/pressure to "draw"

The algorithims and technology that Microsoft is using for their TabletPC XP stuff is specificly written by them for XP, you'll not get anything like it anywhere else until some "other" genious writes an open source algorithim based upon this technology or rather non-patent pending ideas.

The device is nothing new, and the hardware really isn't anything new. What is new is the new algorthim for converting handwriting into text. But personally I would rather save my handwriting as is and not covert it. If that is what you want, you should be able to come up with something that does this with whatever hardware device you can get.

Here's a paper written by a guy studing the problem of handwriting recognition, a basis of the theory and books to where to find out more information, not an algorithm per se....
