Must keep in mind its a multi stream service supporting from a few 100kb/s to 6Mb/s so potentially even quite poor performing end user arrangments will work, obviously with a cut in quality.

Yep true, however an end user will expect HD and most wont understand why it may not look like HD if their bandwidth is being used up with other things. This will really only be poor connections (WAN/LAN/WIFI) or multi-user homes to be fair with low max capacity such as 30/10 UFB, VDSL and ADSL. People are used to Sky just working for a lot of things and don't understand that internet connections are often limited & saturated.
