I agree. You have to understand that most Internet communications satellites are in geo-stationary orbit at an altitude of 25,000 miles. With the speed of light limited to 186,000 miles per second and a round trip of 50,000 miles a quick calculations shows a minimum latency of around a 0.27 seconds and that is just signal travel time and not any processing overhead.
I agree, I don't know what is causing this person to have to replace his routers every year, but a high end Asus or Cisco Linksys router can support enterprise loads and functions with DD-WRT. I have had my system running for years with enterprise specific functions. I have also had obsolete WRT54G routers also with enterprise function running in public facilities with huge loads. I don't get the problem this person is having.
1. Install X10 controlled electrical outlets that you can control from either a secured (locked up) X10 keypad or from a secured computer interface. Nothing says do your home work like a dead electrical outlet.
2. Using third party firmware on the router, such as DD-WRT, set up iptables scripts that can either block all network traffic to the specific machine, block all Internet, block selected Internet sites,... using a secured plink call to an on router script (see documentation on ssh and putty).
3. Set up separate non-admin accounts on each machine, one for fun and games and one for home work only. Share document storage area among the two accounts. Never give up admin tot he kids
4. Up to date antivirus software. .
Needless to say, I get lots of push back from my kid and I have not been completely successful in all four. But I have implemented enough so that he is not totally off the deep end (or so I am led to believe).
Being a parent has given me a new appreciation for functioning in a non-deterministic universe.
Fry's here in Silicon Valley has a NAS (Network Attached Storage) box called a Buffalo that provides 1 TB of storage. It goes on sale periodically for under $700. The company also have a range of sizes including 1.6 TB version as well. I would get two of these units, periodically mirroring one to the other and placing the second one offsite.
Didn't we just see a robot powered by a fly digesting fuel cell. The heck with solar power. India has plenty of flies. Just power the school's computer lab with flies.
I know that plugging commercial products can be hearasy on slashdot but I would suggest that you talk to VERITAS about their NetBackup Professional application. http://www.veritas.com/products/category/ProductDe tail.jhtml?productId=nbupro&_requestid=80144
IBM has one of the strongest Intellectual Property departments in the computer industry. They are extremely agressive about patents.
In the 1960s IBM developed the first virtualized OS on the IBM 360 mainframe (360/65 or 360/85??). I learned about in graduate school.
At the very least there is much prior art via IBM. Also I would be very suprised if IBM did not patent this in the 1960s.
I believe that Ingress had a development tool for X that provided front ends to applications during that time frame. Take a look at the database conference proceedings in the 1990/1991/1992 time frame.
BTW, Ingress is still in business after many incarnations.
I am confused, doesn't 2015-1952=63 and not 67? Am I missing something here?

I do four things for my kid.
1. Install X10 controlled electrical outlets that you can control from either a secured (locked up) X10 keypad or from a secured computer interface. Nothing says do your home work like a dead electrical outlet.
