No, that's not it. LightHTTPD does not speak the RTMP protocol, it
only knows how to seek to a given position in a FLV file given a
timecode. People have been doing this for a while, even in PHP.
IIRC there's only one open source RTMP server, Red5, but that's only
really worthwhile if you're trying to do crap with webcams or
microphones, or connect users together (stuff that you would normally
use XMLSocket for).

Yes, Flash Media Server is a dog. Red5 probably is too, and I'm not
even sure it's mature enough to actually use it in production.
Proxying would work just fine though. One feature that might
facilitate good support for this would be if X-Accel-Redirect accepted
an offset... so you could calculate the offset with some scripting
language and serve the rest of the file with nginx.

Can't it play mp3 files as-is these days?
