Squeak on handhelds

  I notice there's a fairly large number of CPU ports for squeak, and I 
think I saw an ARM port out there somewhere. So, questions:

  - Is there support for pen input? Recent versions of X11 support pen 
input, if squeak were run on top of X would squeak handle pen events as 
mouse events? What about the three button mouse issue with a pen?

  - Are there versions of squeak which will paint directly to a frame 
buffer, or does it currently need an underlying OS with graphics like Win, 
MacOS X, X11? 

  - Is anyone working on a handheld computing project to incorporate 
squeak on the Nokia 770, iPaq, etc? If so, is the project just to get the 
squeak dev environment running, or are the developers targetting a whole 
handheld environment (calandar, note taking, names and addresses, email, 
etc)? 

Thanks much,
