Actually, the Mac client has had the ability to buffer 500 blocks for
a while (enough to keep a current low-end Mac going for 2-3 days), and
the newer clients that have come out for various platforms (the BeOS
client being the only one of these that I've seen) have the ability to
buffer 1000 blocks.

This isn't possible on a Mac (because there's no personal proxy for it
yet), but luckily there are other solutions for Macs (for example, you
can use a Mac program called RC5 Feeder to run a client off multiple

Well, we still need a *lot* more CPU cycles to get this thing cracked
in a reasonable amount of time. Assuming a constant 10,000Mkeys/sec
for the rest of the project (we hit a peak of 9999.12Mkeys/sec or
something similar sometime during the weekend, according to the proxy
server stats), we'll still need almost 60 years to scan all of the
Big companies have lots of computers that are often idle for much of
the day. While Bovine is gaining in speed by itself, we'll get an even
bigger gain in speed if we can get thousands of idle business

Actually, v3 will also let you do different projects (such as Mersenne
There are two ways of interpreting the original poster's question:
(a) How is the stats system going to work?
(b) How will the RC5-64 stats be affected (for example, will it slow
down a lot because lots of people will switch to Mersenne Primes or
I don't know the answer to either question, though.
