My understanding is that the company formed by Randall Bills, Loren Coleman, and a number of others - In Media Res -was formed to be a legal entity required for the move of the BT licence from FanPro. Catalyst Game Labs is an imprint - 'Brand Name" - of IMR, which does the business of making games. If there weren't so little money involved, I'd say it was for tax purposes :)
The fact that there's more than one company called In Media Res should hardly be a suprise, especially when that company's in another country. True fact - the company I work for comes up both as what we do, and as a major US chain of old people's homes. Linked? Nope. There are only so many words in any language.
And IMR (Seattle version) doesn't need a web presence; it's mainly an accounting construct, along the lines of a 'shelf company'.
So conspirasphere, calm down. Seattle IMR didn't "lose" the domain - it never needed one. It has fronts like CGL that do, and that do.
And good luck to all constipated Japanese, may their IMR serve them well! O0
