On the server or the client side?

On the client side you could use one QLocalSocket per thread.

On the server side you can use the incomingConnection(quintptr) template 
method of QLocalServer and create the actual QLocalSocket in the target 
thread's context. We do this in Akonadi, see 
kdesupport/akonadi/server/src/akonadi.cpp and 
kdesupport/akonadi/server/src/akonadiconnection.cpp

Cheers,
Kevin
