The DOCSIS residential gateway vendors seem to have converged on ds.lite, 
probably because it was the first one out the gate. I've seen support for 
this on RGs for other WAN technologies. It's not great, but it's what has 
the most support in devices available.

Lots of ds.lite is in Germany, and most/all the cable operators there have 
converged on ds.lite. This is not uncommon that several operators in a 
country converge on a similar strategy. Engineers moving employment 
between operators bring with them the know-how and do the same thing over 
again at the new place, and also there is a kind of "herd immunity" 
against customer complaints if your deployment and service offering has 
similar properties to most of your competitors in the country.
