Once upon a time, Indy had a larger dev team, but I suppose no-one ever had the time or opportunity to implement SSH. Not that it is a trivial protocol to implement, what with encryption and all. Now I'm the only dev left, and I definitely don't have the time to do something that large-scale on my own. I don't even have a working SChannel IOHandler working yet, and that is just using a few (albeit complicated) system APIs. I suppose someone could write an IOHandler wrapper for libssh or similar library, though.
