I sort of wish someone would build a new generation of mix net without SURBs. I guess SURBs could strengthen identity-hiding for recipients and mailboxes, if Tor isn't sufficient. But I think of Pond (and Petmail?) as "relationship-hiding" systems more than "identity-hiding". And to obscure the sender / mailbox relationship, all you need is the forward direction of the mix net. Looking over Mixminion it seems like SURBs add a lot of complexity and problems with stale paths that would be nice to avoid.
