Science had a nice article in the May 11 magazine. If you have access to them, or a subscription. http://www.sciencemag.org/content/336/6082/660.short The part that addresses your question is: "In 2004, scientists observed the transit in white light, he says. This time, Widemann and colleagues will have nine portable 10-centimeter telescopes at sites including Japan, China, Australia, and Hawaiisome of the best places to view the entire transit (http://venustex.oca.eu). Each telescope will observe the transit through a variety of color filters." If you have no access, contact me offlist, and I will send you the article offlist, I just don't want to publish the entire thing. Jo Quoting Chuck Hards <chuck.hards@gmail.com>:
I'm guessing that a Venus transit from the close vantage point of earth would produce a brightness drop somewhat similar to a giant exo-planet orbiting it's star very closely, as seen from here.
If we could record the transit from the edge of the solar system, it might be useful for comparisons, but we are too close to Venus for it to be similar to an exo-planet situation. It subtends too large an angle.

All,
I was wondering if anyone has heard of any university or observatory that have research planned around the transit of Venus. It seems to me that it would be a great time for a comparative study of the change in light curve of the Sun at the Venus transit and compare this with Earth-like exo-planet transits. Also, I think it would be a good time to do spectroscopic studies of Venus' atmosphere with the sun behind it with today's technology. Has anyone heard of this being done?
