TriTeal Corp, which began life selling a Unix graphical interface, is morphing into a Citrix Systems Inc add-on shop. Its WinTed products (which already support Citrix WinFrame and Network Computing Devices Inc’s WinCenter) are superseded by TealView, to which it expects most of its installed base to upgrade. Using the Citrix ICA independent computing architecture push protocol, which extends NT applications to multiple older Windows desktops and other clients, TriTeal says TealView can provide comprehensive cross-platform services unavailable from NCD or Citrix. Available first on Unix, then on Windows, for Unix-to-Windows and Windows-to-Windows connectivity, the company claims TealView provides a single desktop view where Citrix and NCD launch a session to access the server and another session within that to access an application. In addition, only a single instance of an application is opened. Unlike Citrix and NCD, if Microsoft Word is already open and the user accesses another W ord file on the server TealView won’t open a second version of Word, it open the file as a second window in the same application. Moreover, TealView is claimed to provide unique file sharing and file-type configuration services and gives the user only the icons he or she needs. For newer Windows desktops competition will be Microsoft’s own Remote Desktop Protocol, formerly T.share, which TriTeal says it can’t see Microsoft actively pushing. It doesn’t see a threat from Epicon Inc’s management s oftware which Citrix is integrating. TriTeal recently paid out $9.5m as part of an $11.5m class action lawsuit settlement.
