Since iSlsk was released I've been thinking of this app. Obviously it'd work sepparetely from iSlsk.app, it's all about an iTunes library reader/editor inside your iPod touch. What it should edit? Basically everything that it's editable through "Edit Info.." in iTunes' options (Name, artist, album, volume, etc). The artwork, which would be the hardest thing to do, shouldn't be that hard to do, since you've the Safari Plugin which downloads set-up kind of files and so does IMGrab. After it's on yours device memory, should be the same as iTunes, just add a file browser and we're done. Sorry for any kind of mistake, I'm writting through my iPod. I hope you got what I meant with this app.
