This is a very impressive project, thanks for post. The virtual VLBI system is intriguing to say the least and I'm curious to see just how far this technology can be pushed, I would also like to say thanks for the link to the site, it was new to me and you can be sure its in my bookmark folder now. After reading the article I naturally have a lot of new questions and will likely be returning to comment your post in the near future as I get to look into the subject a little more thoroughly, for example the term "Active galactic nuclei" is new to me and the first thought that comes to mind is, is this a new name for a Quasar or what ? If missions proceed as planned I believe the next 20 to 30 years of next generation space based telescopes along with the projects in the Atacama as well LISA etc. are going to give us resolution to spare, as well as a challenging amount of data to process.
