Wikipedia has a good article on twisted pair (excerpt below):


  In balanced pair operation, the two
  wires carry equal and opposite signals
  and the destination detects the
  difference between the two. This is
  known as differential mode
  transmission. Noise sources introduce
  signals into the wires by coupling of
  electric or magnetic fields and tend
  to couple to both wires equally. The
  noise thus produces a common-mode
  signal which is cancelled at the
  receiver when the difference signal is
  taken. This method starts to fail when
  the noise source is close to the
  signal wires; the closer wire will
  couple with the noise more strongly
  and the common-mode rejection of the
  receiver will fail to eliminate it.
  This problem is especially apparent in
  telecommunication cables where pairs
  in the same cable lie next to each
  other for many miles. One pair can
  induce crosstalk in another and it is
  additive along the length of the
  cable. Twisting the pairs counters
  this effect as on each half twist the
  wire nearest to the noise-source is
  exchanged. Providing the interfering
  source remains uniform, or nearly so,
  over the distance of a single twist,
  the induced noise will remain
  common-mode. Differential signaling
  also reduces electromagnetic radiation
  from the cable, along with the
  associated attenuation allowing for
  greater distance between exchanges.


Twisted pair cable twists and unwanted signals issue
How can I surface TFS 2010 project associated Information with  SharePoint2010, i.e. work items etc. from TFS.

Has anyone surfaced that data in SP 2010 so that the users can access all that info from their team portal? Are there any neat web parts that will let you do that?

Would BCS be requried to surface data from TFS?!
Any insights/thoughts/suggestions welcome.
