I've talked with Noah Sussman several times about selling indie electronics/hardware projects* on Etsy. He says: "Yes, game on!" (I'm paraphrasing.) He's a cool guy to know, regardless.

* I'm potentially searching for a place to sell my "Robot that plays Angry Birds" (http://bitbeam.org/bitbeam-robots-invade-pycon). I go back and forth on whether I should roll my own store, or use a site like Tindie/Etsy/Kickstarter/Inventables, or all of the above. :-)
