One of the top websites I went to for FFXI back in the day, well besides the wiki or allakhazam.com, was FFXIAH.com
I'm not sure how they did it, but they had some sort of API with FFXI to pull all Auction House data in real time. So if you were on your laptop while playing on your XBOX, you could pull up the AH on it to check to see if your items sold... or if you were at work you could see the same info....
Another very useful way to use it was to pull a much longer history of an item's selling prices and who is monopolizing a particular item.
Anyways, wouldn't it be great if the fine folks at ZAM were to make a FFXIVAH.com or something like that... we would be the undisputed king of all FFXIV websites!
Just my $0.02
I wish I were a programmer, I would try to do this myself and add it to ZAM.... maybe someone else here is so inclined... I'm just the idea guy.
I was thinking this today when I was ACTUALLY able to log in to the game for once!
