Right, it's not straightforward. It needs someone(s) to modernise the Haskell ssh lib (see related links at https://hub.darcs.net/#what-is-the-special-ssh-config-i-need-for-darcs-hub <https://hub.darcs.net/#what-is-the-special-ssh-config-i-need-for-darcs-hub>). 

Would me switching darcs hub to use the system openssh server, suitably locked down, be an alternative ? IIRC, I think not; the haskell ssh server allows the necessary tight integration with darcs hub's users and repos. (Aside from the resources required to switch.)
