VXM Technologies Inc, based in Boston, Massachusetts, is in the process of positioning its Network Shell agent system, which is now called Pax, against General Magic Inc’s recently unveiled TeleScript network agent programming language and environment. VXM Technologies says that all systems under Pax are logically identical, so that an agent developed on an Intel Corp-based personal computer can run unmodified on a variety of machines and with a variety of system software. Pax agent development systems for MS-DOS, SunOS, HP-UX, Silicon Graphics Inc and VAX/VMS systems are available and are priced at from $10,000 and personal digital assistant support is to follow, the company promises. Version 2.0 of the Pax fault-tolerant parallel cluster software is priced at from $20,000 for a 300-node system.
