Not sure if anyone else has found this or not, I just did. It's a plug-in for Gimp that allows us to download filters and stuff from Photoshop and use them in Gimp in the .8bf file format.

Works good for the most part. I tried to borrow a filter from the wife's Photoshop on her computer and it didn't work. Filters downloaded from online seem to work good. There are tons of them but it is hard to find some that aren't already in Gimp or similar, but worth a look all the same I think.
