I've linked to an example page ("Servus comes with a clean built-in preview page theme (example)"). It's the real thing, i.e. better than just a screenshot! ;)
I'd suggest embedding a screenshot on your landing page so people immediately "get it". It did take a little reading to grok this concept. Also, I'd suggest a (simple) real-world example rather than "this serves as an example" which almost reads like a snarky response to people complaining it's not there :).
Also, fantastic name and domain. Knowing word's meaning I expected IM/communication app, but most people don't so you're fine. :)
