Roadmap 2023

Mon Jan 2 08:00:00 CET 2023

Hello Norman and Christian,

I would like to shine some light on the parts of Genode that I like
the best and which I think deserve some consideration in this years
road map. I think that Genode shines in the domain of secure
networking. Martin Stein has developed many great components that are
very powerful in this area like the Wireguard component and the CBE
with ADA. I also remember a root of trust device that was planned that
would be very handy and that fits well in this category. In this years
road map I like Christians IPv6 work for the Nic Router as that fills
a hole in the current setup. If this area could get some consideration
so that long term plans for the various components in this range that
still are in the pre-release stage became known that would be great.

Cheers,
Pontus
