Here is a Norway's definition of Electronic Services:
VOES Norway - Definition of the term ?electronic services?
Pay attention to this example. It is the closest example I can find relating specifically to cam sessions:
"
Correspondingly, an educational service that is obtained via the internet in the form of a teacher providing tuition by means of video via the internet will be a service capable of delivery from a remote location that is delivered via the internet and that cannot be provided without the use of information technology. The service will nonetheless not be regarded as an ‘electronic service’ because it cannot be regarded as essentially automated."
