Thanks for the feedback.  Rip, I tried to email you, but when I went to your profile and clicked "Email this person" it said it had been disabled.
Dux: Yes, my company has a process I must go though for any outside employment, including consulting.  I've already discussed it with my boss, and submitted a request for a Conflict of Interest Determination.
banana: First round's on me.
This effort is a fairly small contract, being exploratory in nature.  The offer they made is probably less than I could get if I pressed them (though still respectably higher than my current hourly rate), but if it goes well the company will likely get a second contract for prototyping.  That will be an opportunity to up the ante.  Plus, they're picking up all travel expenses.  So, all in all I think it will work out.
Anyway, thanks for the advice.  Sorry if it came off like blowing my own horn.  Like I said, I was just jazzed to be asked, and had to share it.  It marks a milestone of sorts in my career.  Have a happy Thanksgiving Day.
