Quicksilver SSH host indexer
I used this code back when Quicksilver ran on Tiger (Mac OS 10.4) - it was pretty stable, but I can't make any guarantees that it will continue to work for you.
It probably requires the QS frameworks to be installed (and I don't know how to do that anymore, sorry).
You may be more interested in this thing that I've made in the meantime: ssh_bookmarker - automatically generate
ssh:// bookmarks from your SSH config&hosts files.
