I agree with the whole attention thing and the "WTF" feeling. I've been getting that pretty much anytime my 5-man team is in town since I think I'm the only one on my server that does it currently.

1. If this is just theoretical I don't think you'll have that problem. Just make sure you write down your current key-ID. I'd guess based on the method the programmer actually uses but it may use a hash based on your hardware configuration similar to how Windows uses it's activation, so if you reinstall without changing anything the key-ID would be the same.

If it happens, then just e-mail the programmer with the old key ID, and the new key ID with an explanation. (As per his current FAQ on the website for transferring the license).

2. If you're using /follow your 2nd shaman will always be a few feet behind you, this isn't a problem unless you always edge into range to get max range attacks. Simply bind a key to strafe right/strafe left that does nothing on your primary account so that when you hit it only the clone responds.

Like the name. :P
