The http viewer was written in C68 if I remember correctly. But it was a bit on the slow side, even with a Gold Card. It also operated on top of a "non-standard" windowing system.
The forum is PHP, so that would be another requirement to consider, or something along those lines.
If the goverment has backdoors at the ISP level, a Raspberry Pi isn't going to get around those, unless, using TOR, and even then....
EDIT: then you need some manner of storage for every forum's every thread and every message. Plus users -- I would be thinking of a decent back-end database here, and Archive wouldn't cut it.
I wonder if SuperBASIC would be a good development language to build this system.
Cheers,
Norm.
