Please excuse the top posting.

I did some numbers Linkers.

According to: http://en.wikipedia.org/wiki/FLOPS#Records

Distributed computing uses the Internet to link personal computers to
achieve more FLOPS:

* Folding at Home is, as of April 2010, sustaining over 6.2 PFLOPS("x86"
this is the standard other distributed computers in this section use,
which is different from "native") [13], the first computing project of
any kind to cross the 1,2,3,4 & 5 petaFLOPS milestone. This level of
performance is primarily enabled by the cumulative effort of a vast
array of PlayStation 3, CPU, and powerful GPU units.[14]

* The entire BOINC network averages about 5.1 PFLOPS as of April 21,
2010.[15]

* As of April 2010[update], MilkyWay at Home computes at over 1.6 PFLOPS,
with a large amount of this work coming from GPUs.[16]

* As of April 2010[update], SETI at Home, which began in 1999, computes
data averages more than 730 TFLOPS.[17]

* As of April 2010[update], Einstein at Home is crunching more than 210
TFLOPS.[18]

* As of April 2010[update], GIMPS, which began in 1996, is sustaining 44
TFLOPS.[19]

It wouldn't seem that this initiative was about the combined power of
distributed laptop computers with CPU's apportioned on a protem ad-hoc
chaos theory basis.

P2P Distributed Computer 1,500,000 users @ 8000 TPS = 12,000,000,000 (12
GF) Gigaflops (1.5 million laptop PC's)

By comparison:

Single NVIDIA (GPU based) CUDA Processor 1,000,000,000,000 (1 TF)
Teraflop $1,600
Retail Baby Supercomputer 4,000,000,000,000 (4 TF's) Teraflops $10,000 
IBM's own Roadrunner Supercomputer 1,000,000,000,000,000 TPS (1 PF)
Petaflop	

Cost to build a computer that can carry out the same number of
transactions (on a dedicated processor with 1GB ram) using the CUDA
processor (split into VM's) is less than $180,000.

It would seem to me that the exercise was a data collection exercise by
IBM, whom, to date, have not been involved in mass crowd sourcing social
networking events and may feel that they are missing the boat.

Or, possibly, yet another methodology of decreasing taxation to increase
"margin".

A little transparent, (imho).
