Having finished the core features of Willow CMS I was thinking about starting up a second side project. I was tinkering on my Mac SE and wondered what it would be like to write software on it. It was about 25 years ago that I last fired up CodeWarror on a Power Macintosh 7500 and first tinkered with C/C++ and about 20 since I last actually studied it at university. I decided to have a crack at it by aiming to write a peer-to-peer chat application. I'll start by making it work on Ubuntu, then modern macOS and hopefully in the not too distant future System 6 using the Think C IDE.
