I have recently found myself at the mercy of real life (increased work responsibilities, 18 month old minion, etc) and want to know what the best type of passive income (or combination of incomes) is out there for someone with less time to spare on corp-building, pve, or mining than normal. I'm figuring that maxing a certain research topic and research skills, along with some advanced planet excavation, would be it, but what do others think? Thanks.

I think I've got the closest answer. R&D agents are not a passive thing when you think about travel to retrieve the datacores. However, I have 4 lvl4 agents and 1 lvl3, with connections and negotiation high, and the numbers are 916.77RP/day which comes out to 2,139,130isk/day
...So about 65m a month of almost passive income. This is easy to do with most of the science skills that are used in each region. And the science skill hits lvl5 in a few days. I think this is a decent amount of daily income, even taking into account the flying around to collect the datacores...and I think this is as close as I'm going to get to passive income, and at a relatively low risk.
I’m going with this answer because I’m making close to 160m a month on 3 chars, and you can take the other two chars on an account (if you don’t use them) and just train up R&D skills and nothing else to utilize that unused char. I used to have 3 chars on 3 seperate accounts, now I’m training up all 3 accounts to have 9 R&D skilled pilots with a lot of income that is as close to passive as one can get.

I guess the real question is what is the most effective, and closest to passive, isk income. I don’t really care much about startup costs and effort, but once you get up and running what’s the closest?
