Hi Peter,

With regards to your question about working when out of Internet range all of 
Apples products, such as Numbers, will allow you edit a local copy and update 
the iCloud version next time you get an Internet connection. If you update two 
local versions from different devices you will be warned of a possible conflict 
next time you synchronize and be given the option of keeping multiple copies of 
the document or choosing one over the other.

Apple's way of handling these situations are the expected behavior, but in the 
end each company could handle offline editing in any manner they choose. So 
some less well designed products could in principle make your documents 
unavailable when you are offline. 

Regards,
Carlo
