I suggest using information dispersal to spread risk amongst remailer
operators.  Use Rabin's information dispersal technique to divide up a
document into n shares such that k of them can reconstruct the original,
and post each share via a seperate remailer.  It would be hard for the
government to single out an operator to go after since an individual share
by itself is useless.

If n>k this also increases reliability and resilience of the eternity
service against technical attacks.
