All your explanation of your environment is nice, but you fail to  
explain whats wrong with using the existing approach. Which means  
reusing already available and tested infrastructure with no  
additional work.
You focus on whats great about doing everything from scratch instead  
of what doesn't work for you with the already available stuff.

Eg why do you care about "The parsing is easier", thats completely  
irrelevant given that the parser has already been implemented, plenty  
of times. You need to contrast
a) not having to write a parser at all
with
b) having to write a simple parser
And a) obviously wins, especially given that the implementations are 5 
+ years old in comparison to from-scratch code which needs to mature.


You seem to be focused on going "your" way, despite the fact that  
even JSON-RPC spec dropped that approach. And sure, implementing JSON- 
RPC won't be too hard.
Now thats your choice and I won't attempt to convince you, but you  
can't really expect "best practice" advise or framework support for  
doing things the "wrong way" :-)

Given your background I would choose between two options, either:
a) if speed is a concern, I would use a binary protocol on a socket,
   possibly using shared-memory instead of sockets (you said local IO)
b) if its fast enough, I would use XML-RPC
JSON-over-streams seems to make no sense for your setup in any case,  
since its also slow and its not an accepted standard either.

Anyways, I've even pointed you to a toolkit which enhances GNUstep  
with the streaming functionality you want.

Well, as mentioned thats because its usually not required in real  
world applications. And for the few cases where it is, it doesn't  
make sense to add generic framework support.

Either use a standard solution, an appropriate addon or write your  
own small extension (adding a lookahead stream on top of  
NSInputStream or NSFileHandle is also trivial).
