Scenario: In January 2002, a team of scientists discover a way of building a practical FTL drive, and the first prototype drive, given sufficient funding, could be constructed in 8-10 months. This prototype would be sufficiently powerful to move a 10 ton ship at 1 light year every week. 'Production' models (if they are funded, obviously) capable of being built by 2005 (or about 4-5 years for the slow adopters) would be able to have speeds of up to 2 ly/day for military-grade drives, and 1/2 to 1 ly/day for civilian drives, and could theoretically go much higher, given enough time and money invested. Mass limitations on production versions are much higher, in the tens of thousands of tons. Power requirements are extremely high, and would require either a nuclear reactor or large solar 'sail' array (a la BattleTech) to charge the drive capacitor. Mass of the drive and associated machinery would be comparable to ship-based diesel powerplants, so the larger the ship, the larger the drive. (obviously) The drives can only be engaged in microgravity environments equivalent to at least 200 km altitude above Earth.
The work was done in a US university, with members of the team from Canada, Japan, Britain and Germany, giving these nations the designs and know-how immediately. However, an unspecified source got ahold of the design and theory, and this was distributed across the internet in July of 2002, giving effectively universal distribution to governments, corporations and private citizens. The theory and engineering is no more complicated than a nuclear reactor, although the system does not need the extensive safety measures a nuke does, nor the exotic elements. (Uranium fuel) However, efficient drives require precision manufacturing and extensive computer support for navigation. The drives lend themselves to mass production, like giant computer chips, which would reduce the prices significantly.
How do you think this would affect the geopolitical nature of the world? Would there be a sudden outpouring of people? Would space programs suddenly become fashionable again?
