That's very interesting. I'm curious, what makes an IDN domain rare? I mean, are single character IDNs anything like single letter (or character, I guess) US domains?
Thanks
There's nothing that makes an IDN rare--other than needing the language set on the keyboard, and that's fine assuming you are going after actual words in different non-ASCII languages.
You're probably thinking of random words that are made to look like English. These are complete crap, and unfortunately, are what keep the IDN market hidden from a majority of domain investors.
The "über" valuables are stuff like Игры.com (games.com in Russian) or العرب.com (arabs.com in Arabic) or something like España.com (Spain.com in Spanish--the CORRECT way to type Spain for the Spaniards) [Translations from Google Translate]. Also, don't forget about .net... which in some areas of the world, isn't spit on the way it is around the domaining forums.
Single characters are a bit harder to get into... considering some of the holders want huge amounts of money. I, personally, think they are awesome to own... but hard to monetize vs. keywords. Top keywords have been taken since 2000-2001 in many languages, so there are some alright names available for reg fee, but you have to be one hell of a "miner".
Well, hopefully put out enough information for you to get the gist of the market. IDNs have traffic--not the crappy ones that are sold like "ünderwear.com" or "ügly.com"... as mentioned, only GENUINE words in their intended scripts.

There was recently an IDN.eu landrush. Some lucky people managed to get top-tier keywords for reg fee. Others paid over $10,000 for them at Sedo auctions.
Alright. Goodluck and becareful!
