摘要：The progress achieved over the last three years with e-VLBI has paved the way for the development of the VLBI implementation of the future. At least for the EVN, it is argued that at some point all VLBI operations should be done in e-VLBI mode. This is based on the scientific ambitions of the EVN, which are described in the EVN2015 science vision. At the same time, it should be taken into account that the long-term future of radio astronomy is tied to the SKA. The consensus in the community is that there is a scientific case for Very Long Baseline Interferometry in the next decade, and synergy with technology development for the SKA and its pathfinders should be explored to enhance the VLBI capabilities. I review the progress with e-VLBI, and the options to enhance the sensitivity and operational efficiency of the EVN and global VLBI arrays, including the options for future correlators. New ways are introduced to enhance e-VLBI operations further to the level that all experiments can benefit from an e-VLBI component. It is anticipated that these components will be included in a new proposal to the EC, which will be an important step on the long-term roadmap of the EVN.
