Inter plugin communication

 I'm having some problems with KDevelop interfaces. ;-) The main problem 
is that I don't know how can I communicate between two plugins. Here 
are two examples:
1) Let's have a global plugin called A which wants to print out some 
text to a message view. We have plugin B, which is a message-view 
plugin who is able to process some text and print it out in a nice 
form. Plugins A and B are completely independent, plugin A should 
compile without plugin B being present and vice versa.
Taking the above into the account, how can:
- plugin A send some data to plugin B?
- plugin A request the showing of the main widget of plugin B?

I'm afraid this won't work without creating another KDevelop interface 
for "message-view" style plugins, am I right?
If it is so, I think we will need this and possibly more such 
interfaces. Am I allowed to add those to the platform?

2) The same plugin A wants to send some data to a languagesupport 
plugin.  How can this be done? I mean the data might be processed 
differently depending on what part is active (editor, VPL widget, HTML 
widget) and it might depend also on the type of the language/project 
(C++, Quanta, whatever). 

This is about executing a user action. A user action can output some 
text which can be:
- inserted as-is in the currently edited document
- as HTML in our VPL widget
- inserted in the currently edited document, but further steps made 
(like bringing up a dialog to edit the inserted tag).

It is clear that it is not wise to do all the above stuff in plugin A 
(the user toolbars) as this way the plugin will not be a generic one.
Any idea how to solve it?
