Thanks for your message - it sounds like you're involved with some really exciting projects which could definitely benefit from using FrontlineSMS. At the moment we are in touch with radio stations who are using the platform software without radio customisation to effectively open up two-way interaction with their listeners. You can downloaded this free from here http://www.frontlinesms.com/resources/download/
Its almost a shame about the timing of your trip to Kabul since FrontlineSMS:Radio will not be ready, but I recommend downloading the basic platform for your trial. Once it is set up you do not need access to the internet. Please do let us know how it goes and keep a record of any specific features which you think a radio station would benefit from. As I mentioned, we are developing a specific radio plug-in, so I hope you can disseminate updates to your contacts when this becomes available.
The beauty of the software is that you can use it according to your needs or project, so I encourage you to browse the 'about the software' and 'resources for users' on the website. I would also like to direct you to our sister projects FrontlineSMS:Learn and Medic Mobile for more specialist approaches to the projects you mentioned (click about the project, sister projects for more).
I look forward to hearing your updates about how you use the software.
