I like this idea, but would take it one step further.
ThinkGeek has fairly complete OpenGraph metadata on it, i.e.:
<meta property="og:type" content="product"/>
<meta property="og:title" content="Star Trek Cookie Cutters"/>
<meta property="og:url" content="http://www.thinkgeek.com/product/ed0a/?cpg=fbl_ed0a"/>
<meta property="og:image" content="http://www.thinkgeek.com/images/products/frontsquare/ed0a_star_trek_cookie_cutters.jpg"/>
<meta property="og:site_name" content="ThinkGeek"/>
<meta property="og:description" content="Ready to blast your baking into the 23rd century, this series of five cookie cutters features the symbols of the Federation and Klingon Empire, the U.S.S. Dessert Sur... Enterprise, a phaser, and a Live Long and Nom hand... (Prosper, sorry, prosper.)"/>
If someone were to, say, implement generic support for oneboxing OpenGraph data, all we would need is some way for the community and/or mods to vet domains with OpenGraph support to be added to , then we wouldn't need to pester devs with every little site we think it would be cute/fun/useful to have oneboxed.
