I think this means it is also an end to CrashPlan's peer to peer free backup solution? I don't believe their business plan offers that.

Thank goodness I bought into their long service plan. I have 1.9 years to figure this out.

We have one Linux NAS and a bunch of Windows clients. I could go with Crashplan Business on the NAS and then punt on the Windows clients. Or go back to BackupPC for windows... I hope their windows client solution has improved -- I used to have to install a Cygwin rsync daemon.
