Bind question

[Bettysue]

Ya for use with HKN it would be pretty simple. Bind the movement keys in WoW to WASD or the arrows like you would playing on a single standard keyboard with a single standard character.
Then tell HKN to convert your X-Keys definiton to one of the movement keys you bound in WoW.
For switching in new characters to new positions, just have HKN rename the window dependent upon it's position on screen and like magic your char in the bottom left will move with the bottom left direction keys you have defined on your X-keys.

For instance my current formation setup works like this:
Press Shift+W
w1 gets up arrow sent and moves forward
w2 gets left arrow sent and strafes left
...
w5 get nothing and I now have a cross formation

In your case it would be more like
Press bottom left keys on X-keys and it sends Shift-left
HKN takes the shift left and know this means move bottom left screens char.
so it send the left arrow to bottom left WoW
the character would then move according to its in game keybinding.

HKN script would look like:
<Label w4 local SendWinM WoW4> // these labels are really just a shorcut so you can always refer to a certain window with a shorter easier to remember name
<Hotkey Shift Left> //This is always the physical key pressed -- in your case it would be the output from X-Keys
<Sendlabel w4> // This tells HKN which window(s) are going to receive the key
<key left> // This is the key that WoW will see

I guess it's really just adding the ability to determine which characters receive the keys that differentiates things like HKN, IS and KC from Octopus. I do like your method for overcoming this though it's actually quite clever.

Having never used Octopus I don't know if it's possible to blacklist or ignore certain keypresses, but if it is then you could indeed use HKN and Octopus together, reducing the total setup/conversion time, and you could slowly migrate away from Octopus as you added in keys on HKN. ISBoxer and KC would both be able to accomplish this as well actually, given the abilty for Octopus to ignore certain keys/key combos that are physically pressed.

If you PM me a list of a few things I could send you a script that you should be able to pretty much plug and play.
I would need:
Layout -- how you want the screens displayed sizes locations how many monitors and resolution of monitors. --if Octopus handles this I need to know if it renames the windows at all, and if not I would need to know if I could rename the windows.
The desired actions related to key presses on X-keys and the output related to the actions (bottom left X-key direction pad sends shift left move bottom left char to the left) I could get most of this from your post above if thats the setup you have.
How many comps you play on

With that info I could get a movement script set up for you in a few minutes.
