Is there any possible way to simply connect two or more computers to LackeyCCG using and Ad Hoc?
um isn't ad hoc for ps3? and can't you use direct connect if it's still present?
You can still directly connect by entering a game host's IP, and neither player needs to be connected to the server. That is handy for those rare times the server isn't online.
Said functionality is also usable during times you have no internet whatsoever. All you need is an offline IP to connect to (which will usually require a router; which you'll likely have anyway if you have more than one computer and an internet connection), and it'll work just fine.
Determining local network IPs differs from router to router, but usually if the router has some sort of configuration screen you access through your browser, you can determine IPs there.
