Yes. You can provide your what Intrusive calls NodeTraits and 
ValueTraits to reuse Boost.Intrusive classes (like containers) with your 
own nodes. This allows reusing old C structures or use POD types to 
maintain binary compatibility. You have an example of this in the 
Boost.Intrusive documentation:

Start with this page:

And this one shows how to use Boost.Intrusive with an old C node definition:
