"network" has no meaning here.  using it as a proxy for moving between big 
endian and native endian when there are clear functions that the sim has 
standardized on isn't correct.  your code also (1) requires duplicating branches 
and (2) inline preprocessor checks.  it also does not properly handle bi-endian 
builds.  sim-endian does all of these for you.  the whole point of common/ is 
to delete code from each sim rather than open coding it everywhere.

wrt size, i don't think that's a compelling argument.  we're talking units of 
KiB here, and i can't even count that low :P.

if you're having trouble converting the build over (compiling/linking errors), 
then we can discuss that.  but it'd be a matter of "do we do it now or later" 
rather than "do we do ever convert".
