Jonathan, thank you for your question.
We have an intermediate level "Jesus in Jerusalem" workshop 28Dec 2011 -- 6January. We're excited about this because of the transfer power and 'bang for buck or bang for time' that we've seen in previous workshops.
To preempt an obvious question:
What is 'intermediate'?
It means having covered the basics of the language one way or another AND having multi-listened through Living Koine Greek Volume One, plus at least a few extra listening hours in the 'John CD' with its listening drills on 1John. All the texts and drills in Living Koine Two are also recommended, as well as the Epiktetos CD, but these latter are not a prerequisite for participating. So why do the extra listening? Because whatever fluency/listening level a person comes in at, they will leave at that much higher level.
There will also be another Fresno Workshop around the last ten days of July 2012. Details are still being finalized so registration is not yet open. Registration is currently open for Jesus in Jerusalem.

We are seeing a slow, very slow, awakening in the field. Hopefully, many of us will be able to get together over lunch at SBL, in Greek of course. All levels and backgrounds invited. (There will be a Hebrew lunch, too, on a different day.) We are still quite a long, long way from following meaningful lectures in the language, but one can always hold up the goal and count progress. Meanwhile, we have James Asher addressing the ALBL session this year at SBL to discuss how people can learn multilanguages at the same time in the 21st century.
