Other reason might be that big endian is prevailing endianness used in network
protocols. Think of TCP/IP suite, for example.
Just my 2 cents....

As you guessed rtis is owned by JFCOM/DMSO, and may be coded by
Lookhead martin.
I am not exactly clear about its current status, only thing I know is it is
alive, serves as a fallback rti for JSAF, and it implements SISO DLC 1.3
interface, that's the reason I used it.
In HLA specification, there is nothing says about what endian should be
encoded.
I have found from rtis, it uses big endian. I guess the reason could be that
rtis is for RPR FOM federations that follows DIS to use big endian.
It's your choice.
