I can see the day coming where a home shop will include CNC. Love the opportunity to easily reproduce complex joinery and identical parts.
We are there now, if you are willing to spend about $3000. Check out the CNC Shark sold by Rockler. This price also includes the 3D design software.

I use a CNC router and laser engraver at a shop where I do some part time work. It does offer some cool new opportunities for the woodworker. For me, it is more about creating a custom little part for a "regular" project, and not so much making a project completely usinng CNC or laser etching.
My last project was a super-sized MFT-style top for a 36" x 84" workbench when I bought my first Festool in November -- a TS 55 REQ. CNC helps for repetitive or mundane tasks. I would not have wanted to drill 200 20mm holes manually, and frankly, could never have gotten the precision.
Regarding 3D printing, we played with that for a few months. I think the technology is not there yet, at least for the hobbyist, unless you just want to play. We had a hobbyist machine that sells for under $2000, and in my opinion, was a PITA, and produced pretty crude looking parts. Maybe the machines that sell for 10-100X the price of what we used are pretty decent ... [unsure]
