That seems highly unlikely. Let's assume that all compilers use the exact same padding in C structs, that all architectures use the same alignment, and that endianness is made up, that types are the same size across 64 and 32 bit platforms, and also pretend that pointers inside a struct will work fine when sent across the network; the question remains still: Why? Is THIS your bottleneck? Will a couple memcpy() operations that are likely no-op if your structs happen to line up kill your perf?
I guess to not have to set up protobuf or asn1. Those preconditions of both platforms using the same padding and endianness aren't that hard to satisfy if you own it all.
But do you really have such a complex struct where everything inside is fixed-size? I wouldn't be surprised if it happens, but this isn't so general-purpose like the article suggests.
