I think this depends on the use-case of the software. If everything is going to be Ada, I think all you need is to DSA things. -- See: https://video.fosdem.org/2020/AW1.125/ada_distribution.webm

You can also configure PolyORB to be both DSA and CORBA, IIRC. So, even if you can't directly distribute to the various architectures (which I would be surprised about) you *could* let CORBA handle the remote-calls/translations if you are going to use this with extant non-Ada software (assuming that there's an easily integrable CORBA there).

But if this is integrating new Ada into already extant [distributed] systems, you should take a look at how they're handling the communications. If it's something like UDP then your best bet is probably to go in and create the custom datagram packets yourself, if it's ASN.1 based communications then [IIRC] you can use this: https://www.thanassis.space/asn1.html

There's also the boring case of "reading/writing a binary file" -- if this is the case then you could probably do things via these representation clauses and stream attributes.
