It makes your code look a lot cleaner, but you have to be careful to (a) make sure the compiler packs the struct fields properly
You can do this with __attribute__((packed)) - see http://developer.apple.com/library/mac/#documentation/DeveloperTools/gcc-4.2.1/gcc/Type-Attributes.html. Be aware that __attribute__((packed)) is a GCC extension though, so it may not be supported by other compilers.
