No. OpenSSH uses ptys - it doesn't matter what terminal or console you're using. I don't know of a way to make OpenSSH behave the way you want it to with Windows console programs.

Is this issue particular to OpenSSH, or is ssh-ing into to a windows machine a lost cause in general?

Since non-Cygwin executables don't understand ptys, they think they are dealing with a pipe and so they buffer their output. It's not specific to OpenSSH. You'd see the same issue running these programs under xterm or mintty. I personally wouldn't define anything about this particular issue as a "lost cause" but YMMV. Quite some time ago there was an attempt to smooth out this issue with a utility call ttyfier but it had it's issues and has pretty much disappeared. I don't know of any other aids out there, though that doesn't mean there isn't something . The only things I can suggest are that you make sure there's not some Cygwin utility that does what you want or that you write something that does.
