To sidestep the Biryukov/Pustogarov attacks, one could anonymously lease
a VPS from a trusted provider, and run a private VPN server as a hidden
service. The Bitcoin client would reach the Internet through the VPN,
which would be tunneled through Tor. There would be no Tor exit relays
involved. That would provide some anonymity (limited by the anonymity of
the VPS, considering both payment and management) and also solid
end-to-end encryption through Tor.
