Strange, ... None of the dynamic webpages I wrote can be seen by the user. All my programs either result in pure HTML or provide XML which is then server-side transformed into HTML, again providing only HTML to the client.

Can you point me to a web-site you guys wrote which sends Perl-code to the browser? I assume you are not talking about Perlscript being run on the browser?

Update: Sorry, I read past the part that says the code is deployed on the client's web-site. In that case, the solution is to have a good contract with the client to protect your copyright. Oops, my training as a lawyer is showing.
