I completely agree with Benjamin:

CA should have size-fixed types on the network,

DA should support the native types of its language and convert from/to

the CA types as necessary.

Yes, at some point we will have to nail down CA network format. I

suggest that primitive types for the network layer should be as rich

as possible, /including/ unsigned types. Since each data transfer is

initiated (originally) by the client, communication with a native Java

client will simply never use those unsigned types, thus creating no

problem for the native client. A native Java server, OTOH, will never

expose unsigned data, so a client cannot request it, thus still no

problem.
