I mean writing database-backed multi-user network applications with a web interface. So yes, a webapp, but there's more to it than that. Webapps are exactly that. Database-backed multi-user network applications with a web interface. However, I can understand why you want to explicitly state the context (the phrase lost credibility.) However, an index.php with `<?php phpinfo() ?>` in it is not a webapp imho, but still useful for teaching the network stack. I'd go with Linux, certainly. If they are really bright and aspiring, they'll recognize the power of open platforms anyways. Just my two cents.
