at least with the VLC playhead issue should be solved by 
giving content length in response header. (if you wget the 
file and then host it with apache sending out 
content-length it has a playhead and is http seekable :)

Giving content length would be beneficial for other 
reasons too like generating %downloaded and be more 
friendly to caching/proxy systems ... if just cutting a 
ogg file this should theoretically not be too hard to 
calculate before sending out the stream no?
