Sequel in progress, feedback requested

I'm currently about 90% finished with a sequel to a story of mine, Accidental Research, originally written in November 2004. Last November I started work on the sequel, but hit a writer's block. That block lifted last night, and now the story has gone in a direction I never expected.

Before I submit it to be unleashed on the BI.org masses, I'd like some feedback and/or criticism (good, bad, constructive, gnashing of teeth, etc.). If you're interested in helping, please respond on this thread or e-mail me at doubleintegral@gmail.com with the subject "Sequel feedback". All I ask is that you read the original and not share the sequel with anyone yet.

Thanks in advance!
