Data Files
--------------
There is an issue that has to be addressed by the applications persistence
implementation or any persistence that the library provides. From a numeric
stand point using network byte order consistently should avoid that, or of
course characters.

Source Files
------------------
There is an issue, I know bitfields and unions may be targets for analysis,
there may be more (I have been corrupted for too long by little-endianess)
but avoiding bit manipulation and unions is part of the CoreLinux standards.

Binary Libraries and Apps
------------------------------------
Big issue, I don't know of solutions.


I'm hoping there are some who are running on both type of Linux
implementations (big and little) that we can test/verify against early on in
the development stages.
