If you're annoyed with the Timbuktu floating-icon-menu thing (like i was), you can kill it with this command, in the terminal:
kill `cat /var/run/TimbuktuHost.pid`(the apostrophes are done with the lower-case tilde (~) key). Note that this will also prevent your computer from being accessed through Timbuktu remotely.
tell application "Terminal"[Editor's note: I don't have Timbuktu, so I can't vouch for what this tip may or may not do...]
run
do script with command "kill `cat /var/run/TimbuktuHost.pid`"
end tell
