Interesting, My pondering in regard to Tio was the same as that he and his sister were not welcome to return to Katsuko. (It is likely she still holds a bitter animosity towards both her children). It would be nice to hear that something did become of them, despite the failures of the UOC the characters were developed. Gallivanting off into the unknown tends to be the Motoyoshi way.
As for Katsuko, I was told by a little birdy (CadetNewb) that she was in play (suddenly started getting private messages again when I reactivated my email).
I don't want to get into a position where I am making promises I cannot keep. As long as it is understood that my career has a tendency to take me to Europe, Australia, and South Africa sometimes with very little notice, we should be all good. My ability to stay connected to the internet has been more reliable now that the company is being less restrictive with our net usage on our computers in aboard company housing. But, that shouldn't be much of a problem as that being slow season it will likely be April or May before I see more travel.
I will poke around the IRC when I can. When I am home I work graveyards (cause well, middle of the night here is morning in Europe where the bulk of business is.) so I will be around as I can be.
