Regular use of software translated into "Esperanto" ?

Hello folks,

I know not much about Esperanto, only what I can read at Wikipedia.

I'm member of the upstream maintenance team of "Back In Time" [1][2]. 
Currently the project do partly offer Esperanto [3]. Because of 
ressourrces and maintainability I think about removing that language 
from the project. You might helping me understanding some points about 
Esperanto.

I wonder if Esperanto speaking people do use there software that way? I 
know that Debian offers Esperanto. Do you know about how many users this 
are?

Please correct me if I'm wrong here. To my knowledge Esperanto is a 
foreign (not mother tongue) language to the most people even the 
Esperanto speakers them self. But some do grew up with Esperanto and it 
is their mother tongue language. But it keeps their secondary mother 
tongue language. They grew up in countries where Esperanto isn't the 
primary language. Is there any country where it is primary language?

Am I right so far?

So I wonder if it make sense to translate the GUI of a software into 
Esperanto.

 From a technological point of view: In most cases (except the Esperanto 
Debian users) the system language isn't Esperanto? So Esperanto isn't 
selected by default when installing a software. You have to explicit 
choose that in the settings of a specific software. Right?

Of course from the cultural and political perspective it make sense as a 
"statement". It could be compared to translate software into minority 
(e.g. Native American languages) or "forgotten" languages. But my 
project don't have the resources for "statements".

Hope you can clear up some of that.

Kind
Christian
