VTS enables remote debugging via VTS/IS, regardless of your VTS/IS licensing. In other words, for support purposes, certain Trihedral-supplied debugging tools (such as the "Debugger", "Profiler", etc.) can always be run, even if their use exceeds the license allocation.
Note: Please refer to "VTS Developer's Guide: Browsing VTS Applications on the Web") for even more information on VTS/IS and VIC.
