Well, really all that would require is the ability to send commands to limewire from another program (your web browser) and allow LimeWire to act as a helper application for your web browser. i.e. when you type limewire://SEARCH="program.zip"&CRC="52627245" it would open up LimeWire and run the search. Sort of like when you type "telnet://www.google.com" it opens your telnet client and goes to that URL.
