Thanks for this. I haven't tested, just a short comment:

I believe it is always save to use term-ansi-at-user. There's no need to
check, whether it is equal to (user-real-login-name).

Furthermore, I wouldn't hard-code "ssh". People might have other
preferences, and on some systems it doesn't work. Think about Emacs
running on MS WIndows, where "plink" is used instead of "ssh". Just take
"-" as method, this is a notation to apply user's default (Tramp) method.

Best regards, Michael.
