This is the only info I have about FFXI and Linux but I'm not even sure if you're asking the same thing Bleys was asking in the LJ post.
Thanks for the info Miriel.

Well, if anyone is interested, I have submitted snapshots and testing data of what I've done to get FFXI working using Wine in the link below.

I'm currently the only maintainer for entries to FFXI on that site. If you have anything you want to post, feel free to talk to me anytime or you can also go to the link I just provided and post your entries there. For now, I'll be using all the knowledge I have to get the install and gameplay for FFXI running smoothly using Wine.

Thanks.
