Greetings to you,

1. Well, define "wise." I'm personally not sold on the redundancy argument much myself. If you're saying you don't "trust the survivability", meaning you want to have another computer so that you have some toons up if your main one fails - well, if my computer fails, I'm actually not too concerned what happens to my wow chars, honestly. I'm more concerned why my computer just went north. Now, if you want to do it for performance reasons, I can certainly see that, but I've had pretty good luck with 5 toons on one comp. I say give it a try, and if something doesn't work to your liking, buy a new computer then. You might be like me (was planning to by 4 other comps until I tried it on one) and be pleasantly surprised with how it works on one.

Plus, you can PiP - BOOBS if you use keyclone (leave it up to you to look that up).

2. No problem. That's tons more bandwidth than you'd need. Incidently, the bandwidth used is going to be the same if you use one computer or two.

3. I don't have an xkeys, but read up on it in the hardward forum. My understand is that it works by duplicating keyboard scan codes, so whatever you can do with one or more keypresses on the keyboard, can be replicated with this device. Again, I'm not an expert here.

Good luck.
