Having an http option makes it better for those on restrictive work networks--I'm downloading the file because I want to experiment with it, but I certainly wouldn't want a call from Networking asking why I'm torrenting stuff.
Even in your situation, if you're doing this for work and IT calls you up, you just tell them what you're doing. "I'm downloading a very large file over Bittorrent because it's 50% faster than the HTTP download and I'd like to do some work today. Is that all? Thanks. Bye."
In some places you'd get that call from IT just for downloading a large file. Getting a call doesn't mean you're doing something wrong, they're just checking it's you, not malware, and that it's for work. If they haven't already blocked it, have at it.
