Not insofar as the reverse engineering is used to produce an anti-circumvention device under the DMCA (that is, the reverse engineering itself is still just as protected as it used to be, but that protection does not extend to making the anti-circumvention device available.)
Note that there is still the issue of whether what you've actually is an anti-circumvention device.
> How should I respond, if at all?
If the project is worth the cost of consulting a lawyer, you very likely should do that so you understand better what your exposure here is and can make a more informed decision than you would be able to make based on lay advice you might get from HN. If its not, you should probably take it down.
