Method to share settings/properties between apps

We have a case where we would very much like to share information between two Connect IQ apps. It that something you have considered?

In this specific case, we would like to have an application to configure the advanced settings of a data field. This way we can provide a more integrated feel of the complete application, as it will otherwise require the user to configure the data fields via a web/mobile application... Which will both be more expensive for us to develop and maintain, and it will be a bit counter-intuitive for this application.
