The Google Desktop Proxy from Kent Fitch allows access to the Google Desktop from remote machines.

The basics:

This program is a very simple proxy. A browser or other program on another computer can open a connection to this program which passes the request through to the Google Desktop web server on the same machine as the proxy. Because it is on the same machine, the Google Desktop web server processes the request and passes the result back to the proxy which in turn sends it back to the originating requestor.

The Java program uses a simple configuration file to specifiy the listening port, a log file, and IP addresses allowed access.
