Let me explain a bit how I see it.

From measurements we made some time ago, the overhead of running an 
application in PyKDE is about 8MB once for the bindings. CPU-wise, it hardly 
makes any difference since most of the expensive code is still C++. I cannot 
talk about Ruby, but I would guess it's in the same ball park.

Also, I wrote that we don't want to replace core applications, or long running 
ones. So to run a KDE desktop you won't need any Python or Ruby bindings, you 
can live just fine without those apps.

For things like Kcontrol modules, for example, that's not really a problem. 
The advantage of it being easier to write a module for a specific purpose 
outweighs that disadvantages. I don't think this would form a barrier for 
getting some parts of KDE running on your watch -- as long as your watch does 
not need a mountconfig utility ;-)

Which language? Well, I'm a Python guy, but I wouldn't have any problems with 
a Ruby application ending up in one of the KDE modules that get typically 
shipped. Anything free is basically fine with me, although I wouldn't like C# 
to be ending up being that language. Not that its chances are particularly 
high anyway. That doesn't mean that it wouldn't be good to have at least one 
language that is easier to write and deploy supported by KDE. The win in 
terms of development time is tremendous and we can tap into a large pool of 
developers that previously haven't really been able to write KDE software. By 
exercising the bindings in that way, we would make sure that the bindings are 
of high quality as well.
