The ePetition aspect of Interactive Democracy could be usefully employed for generating suggestions and measuring support for them in areas other than politics. For example, the military could use this system to get feedback and ideas from personnel at every level. Political parties, unions, or any other organisation may also like to take advantage of this aspect of the system.
There could be a small charge for organisations to use the Interactive Democracy infrastructure, but the content generated would remain confidential, open to its members or perhaps only to senior management (the military would need to be especially careful about security).
How would it work?
An organisation would supply a database of approved members who could then use standard security settings to access private areas of the ID site. The organisation may decide in advance if the system is to allow anonymity, or not.
