OK, I downloaded the Squeak plug-in and I seem to be able to  
access .pr files stored on other sites. But how do I deploy a Squeak  
project as a plugin? I think the questions I need answered are:

1.  What does the server (Apache) need to know in order to serve  
Squeak projects as files? Anything?
2.  Will detection of the plugin be semi-automatic? I.e., if a user  
without the plugin tries to download a Squeak project, will he get an  
error, an ugly binary dump or something meaningful?
3.  Anything else I need to know about deployment?

Thanks.
