I think http://developers.curl.com/message/1349#1349 will help point you in the right direction, although the documentation is still skimpy and there are probably bugs with the beta version. In particular that other post says "Earlier versions of Curl also supported offline operation. For this release we enhanced the procedure occ-install-or-update so that you can pass in icons and other information used for desktop installation. Look up occ-install-or-update in the 7.0 Beta documentation to find out more. Also, you can look up the index entry for OCC. We will try to make this information easier to find in the next beta. One other change we made in this release is that when an application is installed for offline operation, the RTE always runs the code stored locally on the client. This means that the applet will not be interrupted if you disconnect from the network while it is running. The code on the client is updated each time the applet starts up, if an update is available on the server."
