There has to be some sort of way to safeguard the buyer from undue taxation by private companies given the hours and the sweat and the blood and the tears and the extreme, extreme expense (in terms of time) that goes into making a decent salary.

Isn't that so Mr. Milman?

If you want to teach PHYSICS, I recommend against digital circuits. There is much more Physics to learn from Analog(ue) circuit design and implementation. Indeed the first circuit I ever built was an AM radio reciever, according to instructions found on my school Physics textbook: "Physics for Today and Tomorrow" by Tom Duncan (IMHO the best Physics book ever) The component count is very low, about 10 components... the most expensive and difficult to find? of which are the the ferrite core and the variable capacitor. An AM radio receiver can be used to teach about electromagnetism, resonance, electronics, etc. Students wishing to go that extra mile can attempt to also build an AM transmitter (this can be even easier to build.)

As in going to work instead of me?

Yep,

Mirroring is not backup I agree.

Once I tried this at home...

Had a backup server where I kept my data, the server had a mirror with 4 disk; each disk had a copy of the data I was working on. Data was written to snapshots on a mirrored partition before being commited to the main partition in order to avoid losing data due some server management mishap. Data was written on this server through CVS to have more control over changes to data.

Guess how I lost my data?

The server got knocked off my desk and slammed hard against the floor!

Well, if you showed me some dough I "might" remember sir.

Just imagine this scenario...

1) You have the blueprints and technology
2) Hide blueprints and "forget" about technology
3) Ask for budget to redevelop
4) Redevelop using hidden blueprints
5) ???
6) Profit!
