The news is that there are no news :-)
The FFI patches published on  are the last version I've developed,
and we're using them daily here at CRS4. Based on our experience, they
are stable. Blocking calls are a feature, and not a bug (the FFI does
*not* want to replace the Erlang driver interface, but just simplify
some common cases of native function calls).
Since we are still using OTP R11B-5, there are no FFI patches for OTP
R12B (yet). However, I've received some feedback, and one voluntary
developer is (was?) actually working on porting the patches --- but
nothing has been released so far. If nothing changes, I'll work on it
when we'll switch to OTP R12B.
Regarding a possible timeline, the FFI has been defined a "tentative
goal for 2008" from the Erlang/OTP Development Team at Ericsson . If
I receive some feedback about the EEP 7 status, we (at CRS4) may decide
to change our priorities and work on the R12B FFI patches sooner than
 Foreign Function Interface for Erlang/OTP
