I'd be interested to see such methods. I did hunt around for 
implementation of networking methods in GNUstepBase however I could only 
find method stubs - no implementation. Then I found ETSocket in EToile, 
and extracted that class and got it working in gnustep-base sans SSL. I 
was doing this for a Raspberry Pi install, where there is GNUstep, but 
no libdispatch.

While we're on the subject, I found Apple advising not to use 
NSFileHandle for sockets... 
https://developer.apple.com/library/ios/documentation/NetworkingInternetWeb/Conceptual/NetworkingOverview/CommonPitfalls/CommonPitfalls.html 
and the section titled "Do Not Use NSSocketPort (OS X) or NSFileHandle 
for General Socket Communication".
However, so far as GNUstep and ETSocket are concerned, it seems to me 
that NSFileHandle is connected to standard POSIX sockets and so there 
should be no issue.
