This is not a portlet problem; it is really just a generic data
update/refresh problem.
I don't think that you actually care why the page needs to be refreshed.
All your receiving portlet needs to find out is whether it is displaying
stale data.
The portlet that makes the change also does not care who reads it
(portlet, webapp, batch job, etc.), it only needs to set a timestamp
somewhere so that anyone who wants to know the date of last update can
get that information.
Could you not set a timestamp in the service that holds the data.
The user page could query the service on a periodic bases and get a
timestamp of the last change time and compare it with its latest update
and then just ask to have the portlet refresh its view using the update
information?
This might involve some Javascript but I would be surprised if there is
not lots of examples of this floating around.

Hi Sachin,
As far as I know, there's no special support for your use case in Portlet 2.0.
Portlet 2.0 specifies portlet event but it's usually limited to one page of one
user. Portlet events are not shared between pages or users.
