Because the caching logic is not identical; hash-forms are global,
rather than client-specific. If Psi and Exodus have precisely the
same capabilities, they will generate the same hash and I should not
need to re-query it, even if they have different caps nodes.
That said, I think we can come up with some simpler logic. If a
given token is prefixed with 'h$', for instance, we know it's a hash
and should be both validated against the result, and -- if it matches
-- cached globally instead of per-client. But for backwards
compatibility, a disco on node#h$<hash> would still give you the
proper results, and COULD be cached on a per-client basis.
