*update 10:55am 21-Mar-08*
I have decided to use the following code instead as it looks a bit cleaner, and more up-to-date.
Tested on Firefox 2 and IE 6.

document.onmousemove = mouseMove;

function mouseMove(ev){
	ev           = ev || window.event;
	var mousePos = mouseCoords(ev);
}

function mouseCoords(ev){
	if(ev.pageX || ev.pageY){
		return {x:ev.pageX, y:ev.pageY};
	}
	return {
		x:ev.clientX + document.body.scrollLeft - document.body.clientLeft,
		y:ev.clientY + document.body.scrollTop  - document.body.clientTop
	};
}

Memcached StartupItem for Mac OS X

Here is an OS X StartupItem for memcached...

/Library/StartupItems/Memcached/StartupParameters.plist

{
  Provides        = ("Memcached");
  Description     = "Memcache Daemon";
  Uses            = ("Network");
  OrderPreference = "None";
}

/Library/StartupItems/Memcached/Memcached

#!/bin/bash
#
# /Library/StartupItems/Memcached/Memcached
#
# Script to startup memcached with OS X. Tested on 10.4 Tiger
#
# To enable, copy this file and StartupParameters.plist to
# /Library/StartupItems/Memcached and add "MEMCACHED=-YES-"
# to /etc/hostconfig ... You can then reboot or execute 
# "sudo /sbin/SystemStarter start Memcached" from a terminal
# to start it up.
#
# I should mention that this file uses my preferred development 
# settings. You can edit them before copying this script over 
# or they can be overriden by creating a config file named 
# memcached.conf in /etc, /opt/etc, or /usr/local/etc with the 
# following contents (modified to suit, of course):
#
#   MEMCACHED_EXE=/usr/local/bin/memcached
#   MEMCACHED_PIDFILE=/var/run/memcached.pid
#   MEMCACHED_MAX_MEM=128
#   MEMCACHED_INTERFACE=127.0.0.1
#   MEMCACHED_PORT=1121
#   MEMCACHED_RUN_AS=nobody 
#
# ------------------------------------------------------------------- 
# NOTE: Memcached < 1.2.0 has issues specifying the interface via the
# '-l' switch on the Mac for some reason so if the service fails to 
# start with the following error:
#
#    bind(): Can't assign requested address
#    failed to listen
#
# then you will need to either upgrade to version 1.2.0+ or forgo
# specifying an interface to listen on by removing the references
# to A_INTERFACE on lines 65 and 75 of this script.

One-click connect from cygwin to full-screen Linux (X stuff required)

Optional: execute the following once (see http://hacks.oreilly.com/pub/h/66 for
details), to avoid typing in the password.

set LINUX_HOST=mylinuxhost
ssh-keygen -t rsa
ssh %USERNAME%@%LINUX_HOST% "mkdir .ssh; chmod 0700 .ssh"
bash -c 'scp ~/.ssh/id_rsa.pub %LINUX_HOST%:.ssh/authorized_keys2'

Now, if you save the following as a BATCH file, you can just click it
to connect to fullscreen Linux:

set LINUX_HOST=mylinuxhost
start /min xinit 
xhost +%LINUX_HOST%
ssh %LINUX_HOST% "declare -x DISPLAY=%COMPUTERNAME%:0; echo $DISPLAY;gnome-session"'

NOTES:
1.
Sometimes xhost + does not execute in time. O well. Just close
all windows that got opened and try again.

2.
If you didn't do the step one (ssh keys), you will be prompted
to enter the linux password; this increases the chances of the above
error.

3.
The single terminal window appearing in the Linux desktop is in fact
a window from your PC.
