How about writing the result to the CLIENT socket? Sockets are bidirectional, and the client script is already connected to the server. I don't see any synchronization issues. 
# server
@results = <CMD>;
print CLIENT @results;

# client
print SOCKET $cmd;
@results = <SOCKET>;

Why do you have a separate server and client? Since they are running on the same machine, wouldn't it be easier to just have the client script do the ssh command? The only reason I can think of is that the server script is running as a different user with ssh privledges.
