According to this article 
<http://www-128.ibm.com/developerworks/linux/library/l-keyc3/> by 
Daniel Robbins, the preferred way of doing this is ssh-agent. He 
mentions keystroke loggers and memory dumps as possible ways that 
your keys can be compromised on untrusted hosts. Password auth is 
just as susceptible to keystroke loggers. So, the question is, "Is 
the method described in Robbins' article more secure than the 
alternatives?"
