I like the name Katana as well.

I have an infinite-scrolling rich text viewer using Qt working. Right now it's in Python for rapid prototyping, but I've to Qt 4.6 installed in scratchbox, so it shouldn't be long before it's working in C++ there. The SWORD C++ api looks really easy to use, so I don't think it should be much work to get that side working.

What I've done so far to get more translations into SWORD is to buy a hardcopy of the translation, then use a script to scrape BibleGateway.com and convert it into the OSIS format (one of the formats that SWORD uses). I'd rather not post the script, since it could be used to violate copyright, but thought I would mention the idea.
