There dosn't seem to be a listing for the ip900 - ip950 is listed as a paperweight.
It would appear the only way to get this working in linux would be to run a windows virtual machine... of course, you could experiment with the close relatives: maybe the ip1000 driver will do something
, and then all you have to do is rewrite it to fit
Windows journal is only available for windows tablet pc users - you can export to xhtml as well as pdf or even tiff images (the MS suggested approach). I note that winXP has a reader for native journal files. However, it would appear there may be a proprietary barrier to reading these files outside windows.
The same would appear to be the case for other handwriting style apps.
Since you have a compelling reason to keep windows on this machine, it would appear pointless to suggest converting the tablet to linux.
I did find gnu gournal
and a java-based jarnal
... which present more portable alternatives.
