I've done better than that.
When we had our house re-wired, I had 2 double sockets added, with a switched fused spur off, with a further 2 double sockets.
I have the router, printer and mouse charger on the permanently powered, and the PC, monitor etc off the switched sockets.
At bedtime, I can power off, flick a switch and a bank of switches is powered down.
Our old house had something like the above, but not remotely controlled. It was a board about 60cm tall, with 6 switched double sockets, 6 un-switched double sockets, and a big power switch at the top. This peeped over the top of the desk, and would disable half the sockets.
Admittedly these were all off a single 13A socket, but I had a shedload of development equipment that ran off wall-warts, so the total power & current was minimal, but I needed many, many sockets.
