Currently, most of people use MS DCOM/COM+, Java Bean/RMI, and Corba to do distributed computing over internet. All of these technologies are provided with some tools and intermediate objects to simplify internet development. However, these technologies have one common and fundamental problem that all of the calls between a client and a server are blocked for a returned result (please correct me if this is wrong). A client stays still, and has to wait for a while after sending a request to a server. If the request is a lengthy action, the client application seems to be dead to a user. In most cases, we could use a worker thread at the client side to do background computation for solving this problem. However, this comes with an expensive price, more coding, data synchronization and mess in coding logic. Additionally, I also doubt that these technologies are able to really move data across internet efficiently.
