... I also wanted [range downloads], but then I first used the seq and parallel programs. It's a very unix-y solution, but it turns out ids being integers is great. You may need to install and play with seq and parallel a bit, but this works for me:

episode downloads (echo must be removed for real downloading):
$ seq 4 10 |parallel echo pcd download mypodcast {}
pcd download mypodcast 4
pcd download mypodcast 5
pcd download mypodcast 6
