dnetc v2.9007-486-CTR-03090710 for Mac OS X (Darwin 7.0.0).

As far as I can tell, the client pauses/unpauses as expected. Could
you describe what you mean by "Mac OS X client" ?

No time frame yet. Writing a G5 optimized core is a nightmare, mainly
because the increased instruction latencies adds complexity to an
already unreadable piece of code (the 2-stages pipelined AltiVec cores).
The peak rate of a G5 core would be near 10-11 MKeys/s per GHz,
i.e. 30-40% faster, providing the core keeps the CPU busy on every
cycles. Now if someone want to write an optimized core, the best I can
do is to wish him a good luck.
