I was wondering, how do they sustain such an effort ? I mean, working on GunPG is not exactly a simple task (I guess), so how do they fund themselves ? I understand the donations campaigns, but when that money dries off ? I read that the main dev had to work on other things not related to GunPG. Does it mean that we do have somebody working on GunPG with a sheer level of pragmatic altruism (i.e. working for close to nothing as long as he can feed its family) ? I'd like to know what it feels like to work on GnuPG from the inside...
