encrypting

[Michael Murray]

Seems to me that this is something that could be scripted somewhat easily
using either a somewhat sophisticated bash script, or something in python or
perl.  

It's trivial (though time consuming) to do manually, and I'm always one to
spend the time up-front automating something like this, if it's to be done
often.

As someone else suggested, gpg would be good for this.

Easy to script using SSH, curl, or any other mechanism.  SSH with key
exchange gives you the freedom to upload and download interactively.

Auto-detection using MD5 checksums...

See above.

I don't think that it's that complex to script up so that it happens
automatically.  I had a relatively simple version of this scripted in about
25 minutes, but it wasn't close to prime-time, so I didn't post it here.
