you don't have to install anything to run Live Geometry. Just visit
http://livegeometry.com and it will run in your browser. If you have Windows on the client computers at school, you'll need Microsoft Silverlight 4 (it will ask you to install if you don't have it).
On Linux (honestly I haven't tried it myself) a similar browser plugin should work. It is called Moonlight and can be downloaded from here:
http://go-mono.com/moonlight/. Once you have Silverlight or Moonlight installed, just visit the website and it should work in the browser.
If you want to build Live Geometry yourself and host your own version on the server, just compile the project, create a .xap file and place it anywhere where it can be downloaded. Then, embed it similar to how
http://livegeometry.com embeds the LiveGeometry.xap. View source on
http://LiveGeometry.com to see how to embed a .xap file:
<form id="form1" runat="server" style="height:100%">
<object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">
<param name="source" value="LiveGeometry.xap"/>
<param name="onError" value="onSilverlightError" />
<param name="background" value="white" />
<param name="minRuntimeVersion" value="3.0.40624.0" />
<param name="autoUpgrade" value="true" />

</object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div>
Let me know how it goes at school. Feel free to use this forum for questions and feedback. I'd be really interested how Live Geometry performs "in the field". Also check out
