The messaging part isn't the problem.

The value in Skype, WhatsApp, etc. is the vast amount of work and codebase that goes into punching holes in routers/gateways/NATs to make the internet actually work like it was originally designed.

WhatsApp is not p2p, they maintain a constant server connection which is not a problem for routers/gateways/NATs because its initiated from the client side.
