Yes, the aim of the cocoon portal framework is to support this JSR
somehow (see below)

AFAIK this is not true, IBM originally started the jsr 162 which
is based on jetspeed, then Sun initialized the jsr 167 as a counterpart
to the IBM initiative.
Fortunately, these two approaches are now combining forces in
the JSR 168.

Yes, blocks and "pluggable deployment" are the key words. Cocoon itselt
will become pluggable with its own block concept and either this
or the portlet api or both will also be used someday for building
portlets.

Currently a sunlet is a URI, so you can call anything you want for
a sunlet, like for example another servlet, JSP, a distant server
an internal Cocoon pipeline which calls in turn another servlet
etc. So, the answer is: yes, you can write connectors here, too.

The standard is not yet available and the final draft is expected
in October this year, so until then we can't make any definite answer.
It seems that the JSR is based on the servlet api, so as Cocoon is
(can be used as) a servlet, this should be no problem.
The always working way should be to write a sunlet which calls
a portlet - that should be easy and straightforward.

But perhaps the cocoon portal will directly support the portlet
api - I personally don't like the connection to the servlet api
and I fear that porlets will deal will io streams instead of
sax streams - but we will see. Hopefully I'm wrong :)
