The non-deterministic retention time in the network could probably be solved, but at the expense of some significant complexity. I have not been able to think of a secure way to do it, however. [If the remailers know and trust each other, the problem is easy.]
Remailers using this could be configured to not modify the "date" header until final delivery. Then you can base the probablity of final delivery upon some function of date/time or another header "X-Remailer-Max-Delay-Time:" If you're worried about traffic analysis, it is possible to randomly modify the date/time header by small amounts at each hop.
