George Hunt has recently been experimenting with the XS schoolserver (currently XS 0.7) on various hardware setups.  And he is tracking his work on a blog dedicated to the purpose.  We are now including it in the OLPC Planet newsfeed.

It’s a good read if you have been trying similar things at home or in your own school.  You can contact him with questions or comments through his blog.
