I'm the author (the leading one) of Yandex Live Letters, which is a CRDT-based EtherPad-like thing. Some flavours of CRDT are indeed related to OT. My favorite technique (pure op-based CRDT variant) is very much operation-centric, but instead of transformations (like in OT), it employs per-operation Lamport identifiers.
Based on our new project named Swarm [1] I may say that CRDT and "async RPC" fits rather nicely together.
OT indeed behaves poorly in a highly asynchronous environment. I suspect, that is the reason why Google Docs doesn't have decent offline mode yet.
CRDT (any flavor) is async-friendly.
