@aschrijver it would of course make a lot of sense for you to apply for Groundwork! I hope the fedeproxy grant application DAPSI-fedeproxy.odt (51.5 KB) DAPSI-fedeproxy.pdf (145.5 KB) will be an example from which you can get useful information.
Yes. The original application has a community building aspect but it is less elaborate than what you suggested. And it will be much much more necessary in the months to come, as soon as something starts working at the technical level
