[vorbis] Ogg Vorbis - low delay <50ms ?

[Robert Michel]

Salve, 

one year ago there was already a discussion about
a version of Ogg Vorbis, with low delay enough for
VoIP

>all transform codecs. They require a fairly large block of samples, i.e. in 
>Vorbis you need to input 3072 samples (or is it 4096) from each channel 
>before you can get any output. This could be reduced, trading off quality, 
>but could not be reduced enough.

AAC Low Delay already reach < 20 ms

Ogg Vorbis is great, and I want to work the vision of ross
http://ross.sf.net
come true: a software-tool-box for radiostaion using GNU,
software only.

But for radiostations who want to interview
people sitting far away in an second studio, a low delay 
of the audiocodec would be as important as for VoIP.

Is this feature possible to implement in Ogg Vorbis and
on which position is it on the to-do list?
When would it come true, 1-2 years?

Greetings form Aken,
Rob
