Full-fledged applications featuring secure e-Documents with rich client interfaces run on any Java-enabled computer connected to the network. They can be launched either from Web browsers such as Netscape Navigator or MS-Internet Explorer, or directly from an icon placed on the desktop. The client software is automatically deployed and upgraded using the built-in Java Web Start technology. Most popular desktop operating systems are Windows XP, Linux, Macintosh, Solaris, AIX and others.

Availability of the wireless Internet and new electronic devices such as light tablet PCs or Personal Digital Assistants have the potential to bring the power of e-Document applications to the field. The specific user interface capabilities of the targeted electronic devices characterize the scope and complexity of HTML designs.
