>> Ars Technica claims that file copies are now 50% faster in SP1.
Actually it is only 25% faster when copying local files:
"Improves performance over Windows Vista's current performance across the following scenarios:
- 25% faster when copying files locally on the same disk on the same machine
- 45% faster when copying files from a remote non-Windows Vista system to a SP1 system
- 50% faster when copying files from a remote SP1 system to a local SP1 system"

NAT traversal for UPnP enables UPnP packages to pass through a router or firewall without problems and without user interaction, (that is if that router or firewall supports NAT). It essentially allows any local UPnP device to punch arbitrary holes in the firewall, by letting the firewalled router create port forwardings automatically."

Cluster VM for Java virtualizes a cluster and gives the application a single system image so that the actual handling of objects and threads is transparent to the application. When an application made up of a number of threads and objects runs on Cluster VM for Java, the application is unaware of where the threads are executing and where objects actually reside. Cluster VM for Java distributes the threads and objects among several nodes to achieve high scalability.
I think this summarizes it pretty well, if a single application usese several threads, they can be run on different machines. Quite interesting if they can achieve it with little performance penalty.

"The article also says that cell use may still be banned during landings just to be safe."
How are they going to disable the phones at landing?
If they just turn the microcell OFF then all of the phones on the plane will start to emit at FULL POWER trying to find a new cell. When the tower signal is strong the phones tend to use really low power to save the battery. When the tower is missing they may transmit with up to 2W and this is quite much.
The other alternative is to go and check if all of the passangers have their phones turned off;-)
This paper reports results from wireless chip to chip
communication experiments. Sixteen bit words pass from
one chip to another in parallel without detectable error at
1.35 billion data items per second for a total data rate of
21.6 Gigabits per second. The experiment transmits pseudo
random patterns between chips built in 350nm CMOS
technology. Chips touch face-to-face to communicate. The
same pseudo random data pattern is loaded onto both chips
so that the receiving chip can check the accuracy of every bit
communicated. Each communication channel consumes a
static power of 3.6 milliWatts, and a dynamic power of 3.9
picoJoules per bit communicated. The channels lie on 50
micron centers. Because the capacitive communication
works through covering oxide, ESD protection is
unnecessary. Vernier position measuring circuits built into
the chips indicate the relative position of transmitting and
receiving arrays to assist mechanical alignment. The test
chip includes a Vernier circuit that provides inter-chip
position measurements with a resolution of 1.4 microns.
Background
On-chip performance has been increasing much more
rapidly than off-chip communication bandwidth because
both on-chip transistor density and clock frequency are
increasing faster than off-chip input/output (I/O) density and
frequency [2]. This difference occurs because off-chip
bonding and wiring are about two orders of magnitude
larger than on-chip wiring. On-chip wiring pitch is on the
order of 1 micron, while off-chip wiring and ball-bond
pitches are on the order of 100 microns. The performance
gap between on-chip and off-chip bandwidth makes off-chip
bandwidth a performance bottleneck.
Fig. 1 shows a comparison of the density of I/O pads for
proximity communication versus area ball bonding [2].
Because proximity communication structures use the lithographic
pitch of on-chip wires, proximity communication
can achieve a density about 60 times greater than area ball
bonds.
Proximity Communication
Proximity communication is based on the observation
that faster, lower-cost communication is possible over
shorter distances. We name this communication method
"Proximity" because chips are placed in a face-to-face arrangement with the transmitter and receiver circuits
aligned with only microns of distance between them.
Fig. 2 illustrates two chips positioned for proximity
communication. Because the transmitter and receiver are
close to each other and communicate by capacitive coupling
rather than through large off-chip wires, the transmitter and
receiver circuits are small. Moreover, the transmitter and
receiver pads are protected from exposure to electrostatic
discharge (ESD) events by the top layer dielectric and
passivation. Thus the transmitter and receiver omit ESD
protection, further reducing the parasitic capacitance and
power consumption.
We chose to couple the transmitter pads directly to the
receiver pads [1][5], in contrast to [3][4] in which the
transmitter couples to a multi-chip module (MCM) substrate
trace which couples in turn to a receiver pad. Coupling the
transmitter pad directly to the receiver pad provides a
stronger signal, improving signal integrity and reducing
power.
Alignment
Alignment is a critical issue. Misalignment reduces
received signal strength by reducing coupling area and
increasing distance. Cross-talk also increases with
misalignment because the voltage swings on adjacent
transmitter and receiver pads couple into the receiver pad. In
order to couple the transmitter and receiver pads best, the pads
must be placed in correct alignment. Fig. 3 shows the six
alignment dimensions, three translational and three rotational.
We use an on-chip Vernier measurement system to measure
the relative positions of two chips in the x, y, and
dimensions. Verniers are common in mechanical systems, and
a micro electro-mechanical system (MEMS) Vernier strain
gauge has demonstrated a resolution of 10 nm [6].

The offender is called NAT Traversal

In other words, use something else to backup the files first if you intend to backup them with Windows Home Server
