a possible solution could be to implement my own serializers for
integral types, that use the very same bitwise pattern? (endiannes,
size, etc.)

yes, basically that was my expectation, that I serialize something.
store it, de-serialize it using the _same_ implementation, but maybe
compiled for a different platform, and then it would work fine.

interesting. I'll take a look..
