Certainly. It's possible to do data acquisition with a Commodore 64
too. Just not easy :-}.

You'd probably need to write your own drivers for any interface cards
you need. But drivers aren't the big deal. After all, you can always
use a DOS machine to take the data, time-stamp it, and ship it down a
network interface to you. The big deal is SOFTWARE. I.e., being able to
rapidly develop user interfaces and process that data into humanly usable
Right now my brother is using WonderWare under Windows NT. He hates it
because a bug in one of his programs will crash the entire machine
("Wonders of a common system heap", he bitterly complains), but
there's no way he could meet his deadlines or get decent functionality
via DIY. For one thing, once the data is collected by WonderWare, it can
be shared via embedded "data" objects with the OLE-aware application of
choice. So a lot of the reports are actually done by Excel or Access...
There's no technical reason why such a program can't exist on Linux, but
nobody has done it. The closest thing I've seen on Unix is HP's RTAP, which
still isn't as "easy" as WonderWare (and a helluva lot more expensive).
