What effects would the fast rotation of Altair likely have on any present planetary system?

Would it affect planetary orbits? Would it have had effects on (or be the result of) conditions of the initial rotation of the protoplanetary disk? Would it have different levels of stellar activities (stellar flares, solar winds, radiation) that would affect planets, or their potential habitability? What would a hypothetical planetary system (including asteroids and debris) around Altair be likely to look like? What features would it be likely to have or not have? And what chances would life have in such a system, either to develop, or if the system was colonized by humans in the future? Could its fast rotation somehow be harnessed as an energy source by colonists or residents of the Altair System with sufficiently advanced technology?

Ok, I am working on a sci-fi novel and I am very undecided about Altair as a setting. I am just mining ideas and information. I am wanting to be as realistic as possible, trying to put the SCIENCE back in science fiction, as opposed to the magical transporters, unlimited energy, M-Class planets, and luxury ships of the post Star Trek sci-fi era.

Any information on Altair would be great. Realistic speculations, especial with reasoning or research behind it, would be very welcome. So are links and references. Thanks for any info in advance, and God bless!
