It strikes me as the sort of thing that should be one function of a much larger app. Not a standalone app on its own. If the intention is to make it a paid for service, I simply don't think it's worth paying for. Other people might be willing to pay for it, but I'm not sure exactly who.
Some of the features sound neat. The question in my mind is, how do the jobs on the Crondom server trigger local scripts? Also the name is both cool and terrible: it reads like condom everytime I glance at it.
Seriously though, sounds easy to use, if perhaps a bit overpriced for something I’d mostly want to use on small or personal projects.
