Yes, this definitely works. I already had one multilanguage .avi, but it
was a demo file, I don't know which program is able to produce them. But
the format is capable of it

Yes, because frameno.avi is really a .avi, with frame numbers instead of
a real video codec.

Well... why do you want to reencode the audio dump? The audio dump is the
dump of the encoded audio, its even smaller than the frameno.
You can use this result with -audiofile

Before -audiofile existed I managed the audiostream problem like this:
a) I encoded the video only (using -nosound)
b) Then I created the fameno.avi s but named them framenoeng, framenoger etc
c) ln -s framenoeng.avi frameno.avi
d) menoder -ovc copy -oac copy -pass 2 videoonly.avi outfile.avi

Especially when I intended to take that file with me to play it at a
friends Windows-only box.

Well I'd like to have multi-audiostream support in .avis, too. But I don't
know how to implement it.
