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.

说明：  通用串行總線是一種通用接口，可實現設備與主機控制器（如個人計算機）之間的通信。它連接外圍設備，如數碼相機，鼠標，鍵盤，打印機，掃描儀，媒體設備，外部硬盤驅動器和閃存驅動器。(A Universal Serial Bus is a common interface that enables communication between devices and a host controller such as a personal computer . It connects peripheral devices such as digital cameras, mice, keyboards, printers, scanners, media devices, external hard drives and flash drives.)

License Plate Recognition or LPR is an image-processing technology used to identify vehicles by their license plates. This technology is used in various applications involving security, traffic, law enforcement, public safety and transportation sectors. It mainly uses software code that enables computer systems to read automatically the registration number (license number) of vehicles digital pictures.
