Everybody hopes so :)

Sounds nice, but prof. audio apps have rather rigid latency
demands. It would be helpful to measure latencies and report on the
PlanetCCRMA lists (if you are audio/sound interested at PlanetCCRMA's
level). Fernando Pablo Lopez, the maintainer of PlanetCCRMA, could
outline or even guide you through the benchmarking.

Moving this to the PlanetCCRMA lists, as this is more appropriate
there.
