Finding Every Species
Microsofts slave writes "A hugely ambitious project to find and name every species on Earth within the next 25 years has been launched by scientists. The internet and the development of DNA sequencing technology make the goal achievable, they say."
put a patent on every single one for purposes of commercial exploitation

Good freakin' luck..
:P
As the pesimist I am, I say this is impossible. What about all the stuff that is so deep in the sea we can't even get to?
I think we'd have better luck finding life on Mars.
R4NT.com - A great many people think they are thinking when they are merely rearranging their prejudices.
List of species known gets larger each year...
List of species that aren't extinct gets smaller each year...
The two numbers will eventually meet.
I'll form my OWN solar system! With blackjack! And hookers!
Is that even theoretically possible? Since new species are always evolving wouldn't there always be new species to name?

I should start by saying that I think this is a noble project. The shadow that humanity is casting across the earth threatens to leave all other species in oblivion, except for those we have genetically engineered or deemed economically beneficial.
A major technical problem, however, is trying to define the limits that constitute a species. This is sometimes tricky with animals, and in some families of plants, it is practically impossible. (If I remember my bio 101 correctly from all those years ago). The project sounds similar to what Lineus and the other naturalists were trying to do just before Darwin and the evolutionists bollixed everything up.
I only hope we leave enough other species around so that when we go, the cockroaches inherit a viable planet. And in case they are listening, "we salute you, our insect overlords". Or perhaps an inanimate carbon rod will save us all.
Even heroes have the right to dream
Not going to happen. They would first have to come up with an adequate universal definition of a species, and they haven't done that in the last 150 years (Darwin addressed this issue).
The lack of a definition for "species" is a problem for humans who like definitions, not for nature, which doesn't care if things become hard to define.
Some things, like pornography and race, are just not easily definable. Usually people use the standard of recognition (i.e. "I know it when I see it") which works well enough for most purposes.
The current rate of discovery is a mere 10,000 a year. With an estimated 100 milion species, it'd take, well, forever.
I think the idea is to identify species based on a genomic fingerprint- the usual marker is actually the sequence of 16S RNA (part of the ribosome). They simply collect as many samples as possible and feed them into the sequencer, and then use computers to determine the relationships.
At least that's what I assume from the article. I don't really think this is worthwhile, because it's easy for two organisms to be nearly identical on the sequence level and still be non-mating. You could have a single polymorphism be the only thing separating two species simply because of change in color, metabolism, etc., coupled with reproductive isolation. In particular, 16S RNA is used for large-scale cladistics because it changes relatively little over time, but this means that the difference between an Amazonian Spotted Yellow Frog and an Amazonian Spotted Green Frog may be nil at that level.
If they're looking at entire genomes, on the other hand, the technology simply won't be powerful enough for some time, particularly if they run into weird or huge genomes. Our genome is small compared to some of the projects underway, and the problem with everything on that scale is figuring out the damn repeats.

Haven't they been doing that for the last couple of hundred years? What makes them think the can do it in 25 when a few hundred years of science has just barely scrapped the surface.
There are so many varieties and they evolve so quickly, that it would be impossible to catalog all of them because there are constantly new species being made. Besides, the distinction between divergent strains of a species and different but related species is completely arbitrary on that scale, because they don't have sexual reproduction. In mammals, the ability to produce fertile offspring generally draws the boundaries between species.
Repeal the DMCA!
The cataloging bit is not so much the goal here. Nor is completeness. As you can read in the article, the people who are currently trying to preserve parts of nature can't make proper decisions on which bits to preserve and which to neglect because of their lower conservational value.
Most conservation efforts start with identifying what's actually present inside an area. For a few groups such as birds, mammals, and butterflies, we have a pretty good knowledge of who's present, despite the occasional deer being discovered in Vietnam or the ten or so new bird species Peru has reveiled over the last few years. But in most groups, which actually account for 99% of biodiversity were are at a complete loss. So much for making sound judgements on where to make the next National Parks.
In order to know how much biodiversity actually needs to be preserved to for instance keep speciation going, or to keep extinction at a minimum, we have to get some basic insight into current state of affairs. Again, just knowing what species you're dealing with is a prerequisite if you want to obtain a global picture.
So from a practical point of view, completeness of the database is not essential. Getting our working knowledge of species from 1% to 50% would be a great step forward, and would probably be enough to obtain much better estimates of extinction rates.
As to how to even get DNA from all those millions of species, most of which have such small ranges and thrive in low numbers in inhospitable places, I can't say I have much of a clue either.
They should start asking the indiginous people of the various places they go to about the animals they encounter, especially if they are nomadic. The folklore, myths, traditions, stories, etc. often serve purposes beyond that of creating a basis for religion. Many of them have been created to help them survive the environment they live in. Not only that, but they also seem to allow to live within these environments without destroying them. This is something anthropologists have known for some time now. Western biologists often have the bad habit of dismissing these things, particularly if they are tribal, under the misconceived notion that they are "primitive" and could not possibly understand the plants and animals around them, when in fact it's their vast amounts of knowledge of the plants and animals around them that allows them to survive.
