anonymous anonymous remailers?

Here's an interesting idea... Assume we create the alt.anonremailer.net newsgroup mechanism that Jonathan Rochkind recently suggested (and it worked). Could we then not use the newsgroup, in combination with a net of well-known remailers, to give us the capability to have some remailers at unknown locations by having some remailers post encrypted reply blocks as their "addresses"?
