The source code is free as well. VMTH Computer Services will install and upgrade Netscape on all VMTH computers. An effective interface for this type of open access to it requires an advanced web client that consistently and reliably implements dynamic HTML, JavaScript, and Java across multiple client platforms, including Windows, Macintosh, and Unix.
