I almost gave up choosing twisted until I found this explanation http://twistedmatrix.com/pipermail/twisted-python/2004-April/007517.html
which basically says a remote_method can return a deferred. In this case, the PB server won't return the result of the Deferred back to the client until the server-side callback fires. The result of the remote_method is then returned to the client, which then triggers client side's deferred callback. So, I thought one of the following would be helpful: 1) An example showing remote_method returning a deferred and/or 2) A section named "Server side remote_* methods can be async by returning deferreds" could be added as a 7th item in http://twistedmatrix.com/documents/current/core/howto/pb-usage.html . I spent some quality 30+ hours carefully reading 90% of the http://twistedmatrix.com/documents/current/core/howto/index.html and I do not remember picking this subtlety up. (Or you can point me the right place in doc.) (great doc btw.) Should I submit an improvement ticket for this? I could also make the server side example using Echoer, remote_echo, and deferToThread just so that whoever fixes the ticket can just copy and paste.
