I used the standard libs for that, urllib.urlretrieve to be precise. downloaded podcasts this way, via a simple thread pool, each using its own retrieve. I did about 10 simultanous connections, more should not be a problem. Continue a interrupted download, maybe not. Ctrl-C could be handled, I guess. Worked on Windows, installed a handler for progress bars. All in all 2 screens of code, 2 screens for generating the URLs to retrieve.
