One thing led to another tonight and I ended up stumbling upon yet more stuff.
First, an early article on LU with a big comment left by a Darwin guy:

Some bits from the article:
Side note; here's another article that mentions this: http://www.gamasutra.com/view/news/111208/AGDC_Interview_How_NetDevil_Got_The_LEGO_Universe_Deal.php
Anyway... The comment left on the first article:
The first link is now dead but is on the web archives (it was posted here earlier): http://web.archive.org/web/20141214191125/http://www.talisman.org/~erlkonig/lego/lego-on-sgis/Main.html
The second link is also dead, and not on the web archives - but, I found this, which probably has the same content:

BUT WAIT, THERE'S MORE:

This page also lists a "Connected Worlds: The Future of Digital LEGO Toys" paper, but has no PDF. Its description is "LEGO Digital (SPU-Darwin) white paper".

You have to pay to access these, so I dunno what they contain.
