From our sister site paidContent:UK: Joost has hired an engineering SVP in New York to build a US development hub, as it loses its chief technology officer to the BBC. Dirk-Willem van Gulik, who had built London-based Joost’s P2P TV infrastructure in Holland, will become the BBC’s chief technical architect in February, charged with building a next-generation network infrastructure to deliver dynamic publishing and HD-quality video. Joost has now hired Comcast (NSDQ: CMCSA) Interactive Media engineering VP Matt Zelesko as SVP of engineering. He will be based out of NYC, where he is tasked with building a “second engineering hub”. Zelesko’s Comcast division just relaunched its Fancast video portal at CES. More at PCUK…
