 makes an interesting suggestion:
 {{{
 It would also be nice, if we lengthen the service addresses to accomodate
 more security, to allow hyphens or some other divider character in the
 name
 that will be ignored. This would allow names to be more memorable, even in
 their current form. These characters should probably be stripped off in
 the
 TBB from any Host: headers, at least, to resist using them as a client
 fingerprinting side-channel. There is precendent for this sort of thing:
 gmail ignores periods (.) in the "username" portion of its email
 addresses.
 }}}

 I bet there are complications that we haven't thought of -- the different
 versions of the Host: header is an interesting fingerprint, and similarly
 I would worry about different versions of the same name being handled
 differently by some caches, Tor's mapaddress to virtual addresses, etc.

 Also, if we indeed make hidden service names much longer, then the Shallot
 approaches will be much less effective at making them mostly memorable.

 But I figured we should have an actual ticket where we make some
 decisions, rather than letting it get lost as an old blog comment.
