Ok, thanx for the advice. They do pay me quite ok and offer me stability, so I would be very open about this to my boss. I was thinking about building something unrelated using the same tech first, for fun and possible profit. Then later I can decide what to do. I already did look for another position (at another company) specifically to have more freedom in this regard, and they (the boss) knows this.
