Can I ask the stupid question of what behavior is different with ssh?
It seems like ssh is a subset of xcpu functionality so why couldn't
that look/feel be provided side-by-side? (disclaimer: I don't
understand why someone would want ssh functionality, but I don't see
where xcpu falls short of that)
