ClearCase remote client is a relatively new interface to ClearCase, implemented in a pure java form.

It is initially an eclipse plugin, but there is an additional download that allows the client to be executed via CLI.

When the CLI is setup pointing to the CCRC runtime, a subset of "cleartool" function is available, as the cli command "rcleartool"

The advantages of using the pure java cli client are the following:

• platform support is greatly expanded
• WAN support, as the remote client was specifically created to get around the fact that clearcase was never originally designed to be used from remote locations over a WAN

I am creating this enhancement request to gauge interest in this feature
