Servers are written in C and run on Sun UNIX platforms, SunOs 4.1.3. The software is quite sophisticated.
Fairly unique as a capability, and extensible through new applications (such as Portholes) which exploit the switching features.
Needs client programs that exploit its intelligence (there are some, see below). Software is part owned by Xerox. Servers are single threaded, thus they probably could not handle large sites. Fairly robust but could be improved. Uses Internet services for communications.
The inter-TAS/ communications are currently under development.
