Hi, 

It is up to you. Instant is currently 
a sourceforge project and I am happy to let it stay there. 

However, the only "real" use of Instant that I am aware of 
is in finite element computations (it has been used with Diffpack and is
in use with PyCC/SyFi). It is in combination with code generation in
Python that it is useful. The reason Instant has been seperated 
out of the projects PyCC and SyFi is that I think that separation is a
nice design goal if it is "natual". 

So, whether it "fit in" or not, I don't know. It is in use with SyFi,
but I don't think that is a strong reason for putting it out
on fenics. SyFi uses other packages which are not fenics packages.
