0. singletons are multi-threaded, so your calls will come in on
multiple threads into the same object. You need to make sure your
singleton is threadsafe.

1. I would put all the calls into a single dll although you may want
to break it down into classes that implement specific parts of the
functionality. Making a single object that exposes all your methods
is unwieldy.
