This looks great Keith, thanks for letting us know about it. I’d never heard of the ISRF before, but am happy to see that they offer a diverse range of funding programs and provide support for independent social science researchers in Europe.
I hope that this of interest to some IGDORE researchers and we are happy to provide letters of recommendation or other assistance (e.g. comments on proposals) with any affiliates application.
Next, i would like to see funding cooperation. 
The application for this fellowship is due on August 14th - time to start preparing if you’re planning to apply!
Also, I contacted the ISRF and found out that, unfortunately, IGDORE is not eligible to act as a host institution for this fellowship, as hosts should have a physical campus in Europe. However, I still encourage IGDORE affiliated researchers to apply if interested. You will have to be hosted by a physical European academic institution but according to the eligibility portion of the FAQ, the ISRF can help you do this and it does not need to be arranged in advance:
Applicants are not expected to arrange the affiliation themselves – this would be negotiated by the ISRF post-award decision. Applicants may choose not to fill in the section of the application form relating to the potential host institution – this will not prejudice their application.
