Unless you really, really need sophisticated VTAM connectivity (ie, you funnel people into a session manager and need more function than a dialed terminal can provide) or you're REALLY REALLY tight on CPU on the standard engine side, it's kinda overkill for just terminal support. The telnet servers included with the TCP stack do that function very well and are already paid for.
That said, it works well if you need what it does. It's a great wedge to get an IFL in the door, and once it's there, you'll find more stuff to do with it.
