Hey! MPTCP again!

Back in Jan I wrote a piece about how to actually use MPTCP

But plenty has changed since then. It seems all my complains about the API are now addressed. Maybe it's a good time to actually run with MPTCP again :)

In my private affairs, I realised I need MPTCP less, since I started using tailscale. My SSH sessions tend to last longer when going over it.

My biggest disappointment with MPTCP was that seemingly, you need both the old and new address to be available when doing handover. So you cannot suspend your laptop, go to a different place, and resume the TCP sessions on the new Wi-Fi.

Of course you can do that. There are different timeouts (MPTCP level, TCP (and SSH) keep alive, etc.) to prevent having dangling connections for a while, but they can be changed if needed.
