Having done testing I can confirm that Coms IS using traffic shaping to profile download speeds for non-HTTP services.
Here's a good way to see how much Coms is [censored] you over:
1. Visit http://www.bbc.co.uk/iplayer/diagnostics
2. Run speed test
3. See what your HTTP download speed is
4. Observe that the following thee "streaming" tests yield 50% or lower than your download speed
