I feel the part about it being open source is either misleading or your description is just really vague, even after the update. First you mention the core is open source, then you mention we need a license for which we can pay as much as we'd like. Now that last part doesn't seem very open source to me.
Fair enough if you want to make money with this, that's your right and I don't think anyone will try to stop you. But don't say it's open source when it's not.
Could you explain, if Light Table is released, what will I have to do to obtain a copy? If payment is involved, please explain to me how it is open source. What license will be used (MIT, GPL etc, if you roll your own, please outline the major parts)?
I was confused by this at first also. Open source means you can look at the source code. Sometimes it means more than that (often depending on who is using the term).
