In one of my site I published an article about respiration and included an image from wikimedia. But mistakenly I chose a picture which is not in public domain. Within weeks somebody emailed me and made a big deal out of it. It was just one image still released under creative commons.
That's what I meant by issues when they do it in a large scale.
If you have ideas for both path, List them all and assesss their potential for growth and demand. Pick the one which scores better in both metrics and start building it. You will come across many issues to solve, one of them probably be cash.
Its not dull, inspiring for me atleast. I am also travelling in a similar path. Sometimes feel awkward explaining about my company to ordinary folks. (Their strange, doubtful look..)
What ever you want to do it, do it quickly. As one of the paying customers, I don't want to grow my subscribers in there and have trouble later transferring to another service.
