Bluetooth pens

Hi,

I'm trying to figure out if it's possible to get either the Nokia or
SonyEricsson Anoto pens to work under Linux.

So far, somebody whose URL I forget managed to make it work for
bitmaps - if you use the right special paper, you can write text on
the page, then check a box and it sends a bitmap of it to your phone
as a standard OBEX document.

I want the keystroke information. In real time. I've gotten in touch
with Anoto, who do the software and technology behind it, and am
waiting to hear back. I was just wondering if anybody's done any
interesting hacking.

Thanks,

gopi.
