> They should be looking for the sweet spot between power efficiency, CPU load and latency, but I have never seen that kind of thinking in any of their public communication.
All of the benchmarks I have seen from them validating various techniques also measure bandwidth as well. While they are focused on one particular problem, I feel they do care about not breaking things in the process.

That only works if every stream is using Vegas - otherwise, the Vegas streams will be penalized against the other streams. For inherently background stuff, this is ok; indeed, uTP for bittorrent works on this principle. However, for everything else it is not a viable option.
