Hi Pavel,
Hehe - the WSLs are already reality. Sitecom is a producer of these and you can get another brand from ThinkGeek.
Sitecom device: http://www.sitecom.com/products_info.php?product_id=293&grp_id=1
ThinkGeek: http://www.thinkgeek.com/gadgets/security/698d/
Why in kernel? Well, the device is based on the Cypress Ultra Mouse. So with a non WSL aware kernel the events from the WSL will be merged into the standard mouse input queue which will make your mouse pointer move uncontrollable - it'll jump across the screen in a couple of steps every 3 seconds or so. Quite amusing but not very handy! The problem is described here:

The WSL kernel driver will translate the device packets to a separate event queue.
And you're right. The WSL driver is not a standalone thingy - you'll some userland tools as well. These can be gotten from:
http://www.schau.com/l/wsl/index.html
The tools contains a patch for xscreensaver (patch submitted to maintainer) and a small WSL monitor program which will monitor in-range/out-of-range signals and disable/enable xscreensaver as needed.
