Hi @willguest
You raise a good point! It would indeed be great to offer STUN/TURN on the boundary nodes such that dapps can establish WebRTC datachannels without requiring resources outside of the IC.
At the moment, we are focusing on the new boundary node architecture, which is laying the groundwork for features like that. Once we have integrated the new API Boundary Nodes with the NNS and rolled them out, we can start thinking about additional services. This will take some time, but I will keep you updated as we make progress.
