There's no need to download files or send email requesting information. Channels update themselves automatically and invisibly in the background. There's no need to constantly monitor URLs for updates. Channels are unlike Web sites in that the user can continue to use them when they're not connected, since the information is stored on the user's disk. The fully developed Java applications you can transmit with Castanet can enrich the user experience far beyond applets.
Applications can range from simple utilities to CD-quality dynamic, interactive multimedia.
Since Castanet allows for local storage in a secure directory, users can operate offline, which makes Castanet perfect for users of handheld and portable computers. For example, travelers formerly had to be online to use applets, since they cannot be stored on disk. With Castanet, an application could allow users to collect expenses or project reports while traveling. Upon returning, Castanet could automatically transfer the information to the corporate database. Castanet automatically downloads and installs your application, eliminating the major costs of physical distribution and technical support for installation.
