Hey, @KonektPat can provide more details, but for now:
I think we’ll have that ready in a month or two
There is overhead from the TCP/IP packet headers. We’re considering a UDP protocol to reduce this but we don’t have much of a timeline for that right now.
I think that should be possible
We’re currently beta testing a super cool service that will allow you open up authenticated tunnels directly to your device. Pat can provide more info on this.
