No? I think it's something they want to do, there's a reference to it in the recent blog post[0]: "The new TextSecure push transport is a federated protocol, and inter-operates transparently with the CyanogenMod deployment of the TextSecure protocol to their 10MM+ users a few months ago."
I gotta say, while I can't really fault them for not releasing the software as quickly as I'd wish they did, I do think their communication could be a bit better. I still have no idea how, for instance, the CM integration works on either the user interface or the technical level. The inter-operability may be transparent; it certainly is oblique. ;)
Don't get me wrong, though, I like what they're doing and I'm looking forward to seeing more.
The federation challenge for TextSecure comes up a lot and IIRC it has to do with the fact that it's a SMS replacement so accounts are phone number and phone numbers aren't routable to the user's domain. If I understand correctly it would be like trying to deliver messages after truncating the "@blah.tld" part from a jabber/email address--lots of opportunity for shenanigans.
