ARCEP, the French telecoms regulator,has decided that it wants to regulate Skype as a telco.  See the link here and scroll down to the press release of 15th March.

So, how should a telco be defined? Originating & terminating voice calls? Issuing numbers for receiving voice calls? Deploying switching & billing infrastructure? Market share of calls above x%? Deploying last-mile infrastructure?

Which definition is in the best interests of Sean citizen?  It seems to me that if MVNOs are regulated, then OTT players should be as well.
