So we'd create something that is similar to the KMessageBox API (without the 
QWidget and KGuiItem parameter)? A non-GUI application could make use of a 
lot of the KMessageBox functionality as well.

A sketch of what it could look like:

kdecore:
========
class KMessageHandler
{
public:
	virtual void error( const QString& text, const QString& caption, Options 
options ) = 0;
};

class KMessage
{
public:
	static void setMessageHandler( KMessageHandler* h ) { s_handler = h; }
	static void error( const QString& text, const QString& caption = QString(), 
Options options = 0 );
private:
	static KMessageHandler* s_handler;
};

void KMessage::error( const QString& text, const QString& caption, Options 
options )
{
	if( s_handler )
		s_handler->error( text, caption, options );
	else
		kError() << text << endl;
}

kdeui:
======
KMessageBoxHandler : public KMessageHandler
{
public:
	KMessageBoxHandler( QWidget* parent ) : m_parentWidget( parent ) {}
	void error( const QString& text, const QString& caption, Options options ) 
{ KMessageBox::error( m_parentWidget, text, caption, options ); }
private:
	m_parentWidget;
};
