There's no need to PK-encrypt large blocks of data. You can always
use a symmetric cipher and PK-encrypt the cipher's key info. Nodes are
already using this approach for communicating with each other in 0.4
(DLES-encrypted Diffie-Helman key exchange with the rest of the data
encrypted in a Rijndael PCFB-mode stream cipher).

The current Freenet design was based, in part, on Crowds. Freenet
already does what Crowds does.
