LzLabs was very careful to avoid any infringement: folks working on their stuff had to sanitize their bookshelves, even. Doesn't guarantee anything, but they've been at it a while, certainly longer than PSI did their thing, and IBM hasn't sued, so that probably tells us something. As Steve notes, this is hardly John Moores' first rodeo: he won't have gone into this guessing/assuming he could just do it and get away with it. Like any rehosting, the point here is to capture the value of the existing business logic. That's huge and is why LzLabs and other such approaches (*cough* Micro Focus Enterprise Server *cough*) exist and are successful. So while it's certainly unarguable that LzLabs' play is very ambitious, I'd not dismiss it as silly (not saying you were, but I've heard others do so). To the modern CIO who sees the mainframe as legacy, this kind of thing is extremely appealing. Let's not bother to go into why that may or may not be a valid perspective: the real point is that folks at least think they want this; all it has to do is work well enough. "Good enough is good enough" for most people. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
