  Ah, its not a 'feature' that can be added.  The 'problem' has to do with
  where/how ssl and http work in an ssl connection.  In an ssl connection,
  all traffic is encrypted between the endpoints (ip/port pairs).  The http
  headers (which apache uses to determine which host to give the query
  to in a namedvirturalhost configuration) are encrypted inside the ssl
  connection and are unavailble to apache until after the ssl connection
  has been accepted. But in order to accept the connection, apache has to
  use the correct ssl key, which is normally different for each ssl-enabled
  host.  Kind of a chicken-or-egg problem.

  To host multiple ssl-enabled hosts on one server, you must use either
  seperate ports on the same ip address, or multiple addresses.
