Maybe you can try The Lounge? It is somewhat different than an IRC proxy since it has a web client (that is always connected)
Looks nice, but Orb already exists. Which is FOSS. You might have problems competing if you decide to go closed source...
It's focus may be rdp, but it supports SSH connections just fine. I switched my main driver yesterday from Windows to Debian (Cinnamon). I came out looking for the same thing as OP, Remina fitted right in as an SSH connections manager
I have had issues since yesterday. Seems like I'm getting SERVFAIL responses and some of their nameservers seems to lose connection
That may very well be the case. However, Belgium is just a small country in a very big world where the use of English is quite common. For instance, the European Commission launched a proposal last year on CSAM. One would think that would trigger a 'Houston, we have a problem'-vibe somewhere...
Am I the only one to think it's rather strange that you get redirected to csam.be when logging in to a Belgian government website using your electronic ID? Really, didn't they bother to do a quick Google search to see what CSAM stands for?
For dutch content on Usenet, I can strongly recommend Spotnet. If you are familiar with docker, you will find a turnkey solution here to get you going with spotnet.
Short explanation (from Wikipedia): "Spotnet is a protocol on top of Usenet, providing a decentralized alternative to usenet indexing websites, and the NZB format in general. Spotnet allows users to create and browse private 'newsservers', or decentralized repositories of files and information. Members share spots (file sharing) with one another, similar to the seeding process in torrent sharing".
