I do not see particular problems implementing it with uWSGI+gevent, but
you cannot use django for it (its view subsystem will make mess with
realtime sockets).
basically you will end with something like:
if environ['REQUEST_METHOD'] == 'CONNECT':
s = gevent.ssl.SSLSocket(..)
s.connect()
client_fd = uwsgi.connection_fd()
server_fd = s.fileno()
# wait for data on both end
ready = gevent.select.select([client_fd, server_fd], [], [], timeout)
...
# if it is the client send data to the server
... server_fd.write(client_fd.read(4096))
# else...
... client_fd.write(server_fd.read(4096)
you need to add better check for non blocking writes, but generally this
is the approach i would follow
