Hey Nick.

One thing you'll need to do after downloading the xkbd layout files from Rubybox is to replace them with the newer ones otherwise all the letters will be capital.

They go in:
/home/user/.rubybox/.xkbd_layouts/

No need to replace all of them, just the ones you'll be using.

For me, I only copied over Rightfull.xkbd to that directory.

I think I've got another idea about the weirdnes that xkbd produces.

It will probably take a week to test it out but I'll post my results either way.
