1 Heath,
2 There are actually patch sets out there that can give you "hard" real time
3 linux systems. But they are going to cost you and more importantly have a
4 huge learning curve, because linux wasn't designed as a RTOS.

14 Others, please correct me if I'm wrong on anything.

16 The stock Linux kernel is not a RTOS (Real Time Operating System).
17 There are
18 patchs to the kernel that make it "soft" real time, but not "hard" real
19 time.
20 Some of the current kernel patch sets (CK sources for example) can get
21 close
22 to soft real time.

24 What does your application need to do?
