In fact I once invested the better part of two weeks in trying to 
implement an "active NoGUI" WidgetType based on the means the 
(WidgetType implementations in the) LCL library provide and with a close 
look to the (working) implementation the mse RTL provides.

I failed, due to the very complex and obviously historically grown 
design of the LCL and the RTL (here there is no decent common code base 
for the work-alike stuff that is necessary in the different WidgetTypes 
and in the RTL (such as message queues) ). I finally decided that the 
only worthwhile effort would include a redesign of all WidgetType 
implementations and of the RTL in a way that a central object-based 
interface for the message queue(s) is provided in the RTL and used by 
all (existing and future) WidgetType implementations. This of course 
can't be done by my poor ignorant self, but needs the central "powers" 
as well in the fpc as in the Lazarus crews.

Thus (as I at that time was just doing a research and was not on the 
verge of actually doing a project on that behalf) I gave up. And right 
now the direction of the stuff I intended to design using Lazarus 
drastically changed and I don't use Lazarus at all (but ANSI C) for 
"custom" projects any more. I merely can provide some research results 
and testing programs, if asked for.
