I actually just finished up the site for our league, season starts this Saturday. Basically what Corey said is the way to go. Generate an export from TD in csv format, and parse out the results, and dump them into your website's db. The only thing I have to do is print out a list of players added to the database, and add their ID's to the ID field in TD. Probably a step I didn't need to do, but would rather have mysql assign the id's that way I know I'm in control of it. Our league is pretty simplistic, but you can check out our page here

http://www.nowoodstock.com/poker.cfmjust created a dummy tournament with only two people and some bogus results from TD.
I'm using Coldfusion for my implementation, might make it available at some juncture to the public to download and install on your own site. Right now I have it pretty intertwined with my custom CMS, so not sure how much of that code I want to push out to the general public ya know, but I can mod it out so it's standalone. If anyone's interested let me know, and I'll get to work on it.
