Of course there is. Don't want to blow away your entire 56kbps dialup
bandwidth just for voice conferencing while playing multiplayer games. It
should be possible to voice conference LPC10 while playing e.g. unreal
tournament or tribes2, over a 56k modem.

(In other words, just because YOU can't think of an application for it,
 doesn't mean there isn't one.)

And just because you have broadband doesn't mean you have to be wasteful
with bandwidth. LPC10 could fit orders of magnitude more clients into a
given broadband connection than e.g. ADPCM.
