Follow up question.. The spec doesn't say anything about what should 
happen when the RTCConfiguration dictionary contains bad input. For 
example, malformed ice server urls (SyntaxError is usually thrown in 
this case). It would be nice to have some text that validates the 
content of the RTCConfiguration that could be shared between the 
RTCPeerConnection() constructor and the updateIce() method (since they 
both deal with this dictionary). So what can go wrong and what errors 
should be throw?
