I'd opt for the SecretAgent API, as it will be stable. You can drop a
custom program with Buildroot. If you opted for modifying NM code via
patches you will need to deal with potential conflicts on each NM
version update.

IMHO you won't get nothing more than a small obfuscation with either
method, so it's probably not worth it, but you know better what your
project needs, of course.
