In the interest of working out the idea generating part of my brain, here are some ideas for making money with TempleOS:
1) Make TempleOS the ultimate platform for doing "live preaching" at megachurches. Use it to talk to God directly in front of the faithful on a big projection screen.
2) Use it to take confessions. No network stack ensures privacy.
3) Make interactive Bible teaching games on it. No network stacks will block out temptations of the internet
4) It could be the basis for a spiritual fit bit where one could track one's faithfulness to the Lord on a daily basis. No network connectivity ensures that the information remains between the believer and The Lord.
5) Make a portable alter to a saint and/or the Virgin Mary at the push of a button that the believer can pray to. It could be running in a picture frame in the corner of one's house as an altar to the lord.
6) Possibly allow for virtual burnt offerings, peace offerings and sin offerings In the altar application. It is a temple after all.
7) Use sensor technology to somehow detect sin such as visiting the part of town known to be the dwelling place of harlots (e.g adult entertainment businesses) and pester the believer to confess and ask for forgiveness from god. This could be rolled up into the spiritual fit bit thing mentioned earlier.
8) TempleOS could bring back the old school non internet connected PDA. It could be the holy Palm Pilot platform. With all the sin online and paranoia about NSA spying it would make the perfect gift for one's fundamentalist Christian relatives. I could actually see this selling to religious folks and compulsive gadget collectors if it was priced less than about $50.
