Despite the possibility of delay in repo-based solution, is it cost effective? I mean, in a CDN-like solution we focus on caching(for distributing contents), which in this scenario(real-time communication) is not that usable because we are not going to use the produced data(from the vice-chat application) again, right?

The Kite approach (i.e., using PIT to do reverse path forwarding) is a significant change to the architecture and I still don't understand the implication of this change yet.
