   Yes, the  shell is  designed to allow  this kind  of extensibility.
Programmers will be able to install their own special folder types and
hook  it  into Evolution's  folder  tree  through  what is  called  an
`EStorage' interface.

   In that sense, the Evolution shell  is a bit like Nautilus.  It has
a  virtual file  system-like  structure (the  folder  tree), which  is
extensible and  generates a special  `evolution:' URL space,  and uses
Bonobo controls to display contents  based on the folder type.  So for
example the  Inbox is associated to  the `evolution:/local/Inbox' URL,
which in  turn refers to a folder  of type "mail"; and  type "mail" is
displayed by the `evolution-mail' Bonobo control.

   The implementation is not complete, though, so the CORBA interfaces
to do this are not actually  available yet.  I will be working on this
real  soon though, as  the Evolution  components will  be have  to use
these interfaces themselves.
