Here is my collection of various remote-admin links:

VNC over SSH
SSH key configuration
SSH key generation shortcut
Windows

Putty an SSH client
TeraTerm Pro (requires TTSSH plugin) another SSH client
Cygwin A full suite of UNIX utilities for Windows, including sshd
WinSCP A GUI SCP client

Mac OS 9

NiftyTelnet Don't let the name fool you--this isn't just Telnet, it's a full SSH client including drag-n-drop SCP

Mac OS X

Note: Mac OS X comes with OpenSSH sever and client.
Fugu GUI SCP client
X11 Apple's own X11, based on XFree86

Comparison of remote technologies

	Linux Server	Linux Client	Windows Server	Windows Client	Mac OS X Server	Mac OS X Client
SSH	yes	yes	yes¹	yes	yes	yes
VNC	yes	yes	yes	yes	yes	yes
X-Windows	yes	yes	yes²	yes	yes	yes²
Apple Remote Desktop	no	no	no	no	yes	yes³
MS Remote Desktop	no	yes	yes	yes	no	yes

Footnotes:

1) Windows can run SSHD but that gives you a UNIX shell, not command.com or cmd.exe. This is good or bad, depending on who you are. With something like Putty or Cygwin's sshd, SSH tunnels can be built for both client and server.

2) A properly-configured Mac OS X or Windows box can be an X-Windows server; however, since those operating systems do not use X-Windows natively, there's not too much point in doing so.

3) Unlike everything else on the planet, clients for use with Apple Remote Desktop are not free. $299 gets you the server and a 10-pack of clients.
