A good piece of advice when shopping is to always beware of the places where the price is not well advertised - the fact that the price is not known in advance does not mean its free - and often quite the opposite!

Speaking as a developer working for a company with much less money than
yours, if the IETF selects H.264 as the MTI codec, this will make it
even more dramatically difficult and expensive (if not impossible) for
pretty much everybody else to use webRTC, or at least to develop
services based on it.
