From the client's point of view, the remote call gets another <code class="API" base="twisted.internet.defer">Deferred</code> object instead of that string. <code>callRemote()</code> <em>always</em> returns a <code class="API" base="twisted.internet.defer">Deferred</code>. This is why PB is described as a system for <q>translucent</q> remote method calls instead of <q>transparent</q> ones: you cannot pretend that the remote object is really local. Trying to do so (as some other RPC mechanisms do, coughCORBAcough) breaks down when faced with the asynchronous nature of the network. Using Deferreds turns out to be a very clean way to deal with the whole thing.
