Well.. there is a 3rd party Server out for FFXI.
atm they dont have any means of getting PS2 client sto connect.
the idea is simple a Simple login program that logs into the Servers IP, Bypasses PlayOnline and Directs or Resolves ffxi00 pol com to the server's IP and pp000 pol com to the server's IP, (much in teh same fashion the logan5 tool did for PSN/PS3 Game users when it worked,)
the only thing that i'd be worrie dthat could prevent that would be DNAS.
