Thanks for your thorough explanation. I'm not sure this casting
limitations could be acceptable in future Intrusive developments, but I
agree that Intrusive should somehow be used with non-trivial pointers to
solve problems like the one you're trying to solve. Right now I don't
have enough time to carefully study your work in progress but I
appreciate your effort and I'll try to fully understand all the details
needed to support this special addressing.

Thanks. If you think it will be useful to support it in Intrusive, feel
free to share your improvements in the mailing list.
