TTD #1 for 64, TTD #1 for 66, yet 'someone else' has found the key both times. Have you ever wondered why?
Fastest client? How?
Secure Server? Has it been audited?
Startup scripts. Nice!
But, either way you go, you need to plan ahead and think about items such as:
cracking program to use
server
client
how you will load the client and cracking program on all of those machines and hit "start"; will you have access to be able to SSH into each machine?
ttdpool and ttdclient already have this. Fastest client, secure server and startup scripts.
