I'm working on #2, but the solution I've found is not exactly what Paul suggests. I ran into a need while working on my latest startup.

I'm in bed with a large tech investor for my current company, and I'm working on this tech on the side. My term sheet is such that my company owns whatever I create right now, so I'm hoping said large investor isn't too annoyed with me allocating some time on the side; my plan is to ask forgiveness instead of permission.

Aiming to kick it out to the public in a month optimistically.
