since Interactive Interface is plain JScript / HTML, you could
a) install the three pages to every machine,
b) put them on the class rooms webserver, so anyone could get them from there.
With Schema Editor things are different:
Keep in mind, it’s Java, so every PC needs JVM and I think it’s JRE 1.3 that’s needed with Tamino 2.3.
There is an option in the setup program when you choose customized (instead of full or typical) that theoretically lets you select Client/X-Tools/Schema Editor as the component to be installed. But I’ve not checked if it works. Give it a try.
If it doesn’t work, take an existing Tamino installation, take a sharp look at the setup of the Schema Editor StartMenu link and copy that setup (all the jars and stuff) to the client machine, then configure a batch file to start javaw with the approbriate classpath and stuff. I hope you don’t have to take this approach!
