ZSH Local or Remote?

[Steven Klass <sklass@xxxxxxxxxxxxxxx>]

Hi all,

	Does anyone have a nice slick function to determine whether the  
machine you are logged on to is local or remote?  Basically you will  
get the tty of the current shell and grep for this in who or pinky.   
If you get :[0-9] you must be local.

	Clearly this isn't bullet proof but I was wondering if any of you  
had a really slick way of figuring this out..

Why you ask?  If I am locally logged in I want to run keychain.  If a  
person is remote AND the machine is a trusted_machine I want to run  
keychain.  Otherwise don't...

Keep in mind this needs to run multiplatform - so be carefull which  
command you use..
