[boost] [SoC] project ideas: BigInt

I put BigInt back on the project ideas board with a caveat that some approaches aren't viable due to licensing concerns and that successful proposals should include discussion of those concerns. Out of curiosity, do we have a summary of those licensing issues and other concerns for this project? I haven't had the time to dig through archives. If we're accepting for BigInt, should also solicit a project for arbitrary precision floats? What about a fixed point data structure? Andrew Sutton andrew.n.sutton@gmail.com
