Lighttpd

Is there a plugin / module for lighttpd, that can do LIVE streaming ?
i,e a live capture feed (growing file size), needs to get streamed out over HTTP.
I know mod_flv_streaming, cannot handle this. It assumes the file size is fixed.
Basically, I have a live feed, that is dumped on to a file, an ever growing file, which needs to be streamed out using lighttpd.

I am ready to write/modify new/existing module. I need help in understanding how to do this.
In other words,
1. Is there a way to indicate from a module/plugin, to the network-backend to stream a file, till EOF, without specifying the chunk size ?
2. Do chunkqueue_append_file or http_chunk_append_file take special values in "offset or len" to indicate this ?

I have noticed that there is code under the network backends, to detect a file shrink
i.e (chunk->offset > stat_cache_entry->st.st_size)
But this is the opposite case, where in the file grows !

I havent seen support for this. Hope i havent overlooked something very obvious.

any assistance will be greatly appreciated.
Thanks in advance
