Nope, at least not yet.

You don't care about the advantages, if it's possible under linux ;-)

IMHO the main advantage with 2-pass encoding is, that you can hit a
target bitrate quite easily without playing with -q and -b until you
get the best possible result.

I wonder if it would be (easily) possible to create a filter like the
Avisynth SelectRangeEvery() filter. This way one could encode let's say only
a tenth of a movie in a tenth of the time to get suitable parameters
for the specific movie and then encode the whole thing with that
values. 

For those who don't know what it does: 
SelectRangeEvery(100,10) selects 0-9, 100-109 and so on...
