Re:Yes there is a client (Score 2)

The client for download on the Distributed.net site is a very old version for use on the QNX4 OS. The free download will be based on the QNX/Neutrino OS, and isn't compatible with the QNX4 binary. However we have ported the client to Neutrino for x86 and ppc platforms. A beta of the x86 client has been submitted to d.net and the ppc client is currently being tested in-house. Both should be up for download well before the OS is made available.
