If ogg123 works like mpg123, it will do the sampling rate conversion
internally. In other words it will always output decoded data at the
sampling rate that was set upon startup.

I'd suggest using - for each client (using JACK+ecasound):
ogg123 http://myhost/stream.ogg | ecasound -i stdin -o jack_alsa
Ecasound's double-buffering layer will handle the input buffering (by
default the buffer size is multiple seconds, can be increased to
be even larger).
JACK server will take care of mixing the N input streams to the ALSA
