Discussion on lazer cutting fonts

Anyone here know anything about lazer cutting fonts preferably free ones?
I am trying to set up a discussion on this topic. If you know anything about this or wish to take part in this discussion please post here, thank you.

This is what I found out so far.
" single stroke fonts, such as the ones you'd want if you wanted to write very fine lettering on a surface in vector mode. The only way I know of to do this is by using AutoCAD and its built-in lettering. There's actually no way to describe a true single-stroke vector font in PostScript or TrueType, so no normal program can do it"

One site I looked at liked cargo crate which is more or less a stencil font.

"Cargo Crate. It's a little but tall and skinny so I usually end up stretching it, but I like the look and it's free."

Here is something else I found but do not know anything about this web site.
