 Replying to [comment:4 raimue@…]:
 > If portindex gets faster, we could even generate it on the client side
 only by adding it to 'port sync'.

 Wouldn't that require us to either pay attention to what rsync is
 updating, or to crawl through afterwards looking for newer files?  The
 latter works also for file:// synced via svn.
