TCP is very tough to get right - with this said ,this would be great to help network-deployments where UDP is blocked and other restrictions such as national firewalls apply.

Exciting iff this gets upstreamed.

I expect that the outer TCP might be better for high throughput, low RTT, no loss networks and more or less constant throughput on the vpn tunnel. Probably worse in all the other cases.

Mildly off topic but I absolutely adore this website. That said, I can’t think of any situations where this’d be useful for me.

Curious what kind of networks restrict UDP? Especially since HTTP3/QUIC requires it.
