Extending DataTables Settings?

Hi there,

I just thougt, it should be possible to add some custom configurations to my DataTables settings.
Like this:

$('#table').dataTable({
	"aoColumns" : [ ... ],
	"oDialogSettings": 
	{
		"iDialogWidth": 800
	}
});

After trying out and searching at the forum I found a comment in 2010 by allan:

You are quite correct - that this is something that DataTables is lacking in at the moment.[...]
A future modification will make this much smoother...

Is there any way in the version 1.9 to attach custom settings?
