  6. mStar…. • Complicated user interface • a “techie” system • Only Solaris support (some Wintel support added during the spring of 98) • No good installation procedure • Hard to administrate and upgrade

  7. mStar • Over the years a product demand have appeared • Thus the creation of the company Marratech AB which now holds the exploitation rights of the system. • mStar is currently being modified into a more product like system. • All need for external programs removed.

  12. Work under the Surface • Incorporation of heterogeneous networks • mTunnel • mVideo uses low bandwidth JPEG still images to create a live electronic corridor • Experimenting with different video/audio codecs • Switch from Java Media Framework to own code
