Awesome, talk about hyper efficiency.  You rule!

Personally I suggest just using aliases instead of little shell scripts.
I actually used to do something similar.  My .bashrc would scrape out
the hostnames from my .ssh/known_hosts file and autocreate aliases for
each one.  

However each time I wanted to connect to a new server, it would be
counter productive because I would type the hostname first, get an
error, then type in "ssh hostname".

I have since settled on a balance of efficiency and maintenance.  "ssh
hostname"  New hosts work (because they listen on 22), it's fast to
type, and doesn't require any per-host setup.
