What type of problems do you get with your machine when you leave it that you cant detect on the motorloads?
The available kits on the market cant fulfill my demands, so I think Ill make my own.

Well the smaller one's are not ment to run continuously. I can't run mine for more then 15mins at a time or the motor overheats. Also bits break often, they wear out quickly. The smller cheaper one's don't detect anything, I am not sure the more expensive one do either. We have some Million $ machines at work that don't do that. That would take a hell of a sensor array and a lot of $$$. If the bit breaks they keep on going. Not good. If the program messes up and your machine runs out of travel it will destroy the drive screws and the motors. Thats why most machines have a quick OFF button. Also the mess it makes is not optimal. I run a shop vac with mine to suck up the shavings. There is all kinds of other things that could go wrong.
The noise would be your biggest concern. There is no way your neighbors will put up with it. Also it makes a HUGE mess. Even a small water block makes a large mess. Those shavings get into everything.
If you try it make a large box out of soundproof material. Figure out a way to suck up the shavings as it goes and figure out a reliable bit cooling system. Get a drive motor that can run continuously and make sure the box is well ventalated.. Maybe fireproof also.
Check out the CNCZONE forums link I posted above. All kinds of stuff in there... I plan on modifying my Sherline with a much larger table to do bigger things in time...
