Running a second SSHD on a different port, different config

1) cd into /System/Library/LaunchDaemons
There is a file called ssh.plist in that directory. Make a copy of it:
2) sudo cp ssh.plist ssh2.plist
3) Edit the file ssh2.plist changing the following lines (below is a diff of the two files) but only change ssh2.plist:

--- ssh.plist 2006-10-13 12:06:19.000000000 -0500
+++ ssh2.plist 2006-10-16 11:31:22.000000000 -0500
