Sales quotation offline

Hi 

We are using IFS apps. 10

We want to use the sales configurator in IFS to create sales quotations, but we need it to work offline. The use cases for offline sales work is, 1) Using the time on a plane traveling to a customer site to make a quotation. 2) It happens that you are with a customer where it is difficult to get an internet connection and even more difficult to get a VBN connection.

I have only read about two solutions 

1. Maintaining and distributing a so-called version to the user of the IFS/Sales Configurator client tool - This is not possible for IFS apps. 10
2. Native apps. - This is not developed for the sales configurator

Does anyone know a solution to working offline with the sales configurator in IFS?

Thanks
