My first thoughts are that we'll need to do some research on bringing tools over the border. There may be a tax or something like that when you state that these are 'for sale' and will be sold over there.
We did a workshop up there last time and there was some notice, from the guild, to say to the border crossing guards, that these were personal tools, that we were bringing in, and that they weren't for sale.
I'm sure if Will B reads this he can give up some info on what may or may not happen.

Personally I think it's a great idea, but we'll have to work out the details. I won't be leaving any of my personal tools in a room, when I'm not there, but I would bring some to show and maybe swap.
