I was suggesting to pass the summary-info required for the view as a
dbus object (which requires
creation of an object similar to CamelMessageInfo) which could save
string-vcard convertions and vice-versa in eds and
also remove the need for delayed parsing. But as I do not understand
the use case, the suggestion may not even be relevant..

Ok this gives me some idea. But, use cases would make things clear.
