Hello Daniel!
Thank you for your offer. I like the idea, but i have to decline at this point in time. Please let me briefly explain to you why.
Security is one of the reasons, why all installers are build a public build infrastructure (Travis-CI) and released directly to a public host (Github Releases).
This excludes my machine for a good reason and intentionally.
The project relies heavily on the excellent Github infrastructure for downloads. Its our offical download source.
Still, a mirror system would be nice to have, to be a bit more independent and to avoid a single point of failure.
The main problem is that the installer executables are not code-signed. This circumstance makes secure download mirroring impossible.
Without code-signing, i can not make sure, that the installers are not modified, when a third-party delivers the download to a user.
At this point in time, introducing a secure download mirror system without code-signed installers, is simply not possible out of security reasons.
We may discuss the topic again, when the installers are signed.
Regards, Jens
