Well it's basically Event Sourcing [1]. It's probably also worth mentioning CQRS as well. All this stuff really appeals to my functional programming side :-)

I haven't quite figured out to what extent OT is the same as event sourcing. I guess OT is event sourcing with the additional concept of translating events over the top of other events (i.e rebase).

I'm not familiar with either CQRS and OT. Google fails me completely on the latter, but does CQRS mean "Command Query Responsibility Segregation"?

CQRS: Yes that's it.

OT is operational transform; the set of algorithms behind google wave/docs. A modern take is http://sharejs.org/
