Yeah, almost never feasible with someone else's machine. I more brought this up
to show how one can do a number of handy things with "wildcard" ssh clauses.

Gee, thanks for that idea. I didn't know that was possible. I still
feel uncomfortable about sticking a dongle of mine into a foreign
machine.
That's understandable. Would that they had hardware "readonly" switches.
Of course, you shouldn't be doing this with a foreign machine which you don't
trust to some degree. With a USB stick or with a password, you've got to have
faith that the machine isn't set up to capture your key and/or
passphrase/password.
However, the USB key at least lets you carry a disposable key that you can use
for remote access from a platform you trust.
I suppose if I could find a batch of small dongles I could set up
"one time
dongles" to cover that. Thanks for the information. I just got up and I have
had my daily required learning experience. I guess I can go back to bed.
Seriously, thanks.
Glad to be of service.
