@Mike, well, when we come to that, I'll throw your name on the list, as well. What kind of a printer do you have? You'd need to either have one of ours, or would have to figure out how to integrate the extruder to yours.

The latter issue is something we're going to start talking about publicly some time in the Spring. When we publish, as we promised, the mechanical, electrical,and electronic interfaces between the printer platform and the extruder, we'll be asking the community to pitch in and help create appropriate implementations for many different printers. But that's a conversation for a few months from now.
