I would think that HTTPS is both closer to the TFTP model (ask for a file,
slurp it down over the same socket) than either FTP/SSL or FTP/SSH and also
easier to implement.  If all one is doing is checking if a file is changed
and then grabbing a new copy if needed, HTTP is pretty darn simple, and
there are several HTTPS libraries with BSD licenses one can easily
incorporate into commercial products.

HTTPS also has the benefit that any potential customer can be expected to
already have a server available or would be willing to put one up.  I've run
into a lot of resistance from operators with FTP -- they actually prefer
TFTP if those are the only choices -- and wouldn't want to teach them how to
properly install FTP/SSL or FTP/SSH.

We live in a port 80/443 world.
