Thanks to both of you. Your responses helped a lot to sort my Ideas and
hack up my initial "poor man" / proof of concept solution:

- subsession ids are generated with c->generate_session_id from the
  Session Plugin.
- subsession data is stored as $c->session->{SUBSESSION}{$ssid}
- ssid is picked from $c->param
- uri_for automagically sets ssid
- all internal links are constructed with uri_for()
- change of subsession data doesn't yet cause a new ssid to be assigned.
  This comes later. Up to then it has to be done manually with
  subsession_next.
- You cannot change subsession data after you've shown the subsession id
  to the client (i.e. you've used uri_for).

So far this seems to work fine, but it needs a bit more testing (and
documentation).
