I've recently been trying out the PuTTY Connection Manager and I think it's a very useful tool. What I find most useful is the ability to store the connection information for all of the routers/switches that you connect to regularly similar to VissionApp or RoyalTS does for terminal servers. It is currently a work in progress but the beta version is pretty stable. You can download it for free here: http://puttycm.free.fr/
