Any thoughts from homeschoolers?

It wouldn't be allowed in many states.  Such states require, among other things, a minimum number of days of instruction, following (to a greater or lesser extent depending on the state) traditional core subjects such as English, math, and science, with records kept of what is studied, and many states require standardized testing.  It would have to be an awfully education-rich household for such things to be imparted organically without some sort of plan.

For some unknown reason, my son was reading, and understanding what he read, before he turned three years old.  One day, without prompting, he was reading aloud, of all things, the safety label on a set of gas burners for our fireplace (it's not connected to propane and we've never used it).  Another time, he had a set of wooden letters laid out on the floor and, again, without prompting, spelled... "Quebec".  He's never had the slightest problem reading anything that is put in front of him, and he has always been a prodigious writer.  I mention this because, I suppose, a child could self-educate organically, but such education would inevitably have gaps, some of them crucial ones.

As to record-keeping and curriculum, I created a plan that fulfilled all of our state's requirements, and graded in accord with state standards.  My son's quarterly grade reports and high school transcript (both of which I designed myself) are indistinguishable from those of a public or private day school, you would have to be told that it is from a home school.  I couldn't find any record-keeping tools on the market that did what I wanted to them to do, so I just made my own using a spreadsheet program.  Again, you would have to be told.
