Looking at it shortly, it seems to download them from the PS3SceneFiles' servers. Have you talked with
about it? When its been smoothened a bit more in the edges in regards to what the previous posters here wrote, its a nifty tool you have made.
I could imagine though, after having checked out the ps3scenefiles' homepage that it could be a problem that you use their servers. I can see there is some ads at their homepage, and since your program is used to download the patches directly from there, it might mean lost revenue from the bandwidth at their servers. I believe/could imagine the revenue (although it probably is small) is helped to afford hosting the files there.
