There's no reason to have swap on a RAID0 device. swap on a RAID1
device allows your machine to stay running, even if the drive where you
had SWAP fails.

Not on decent hardware.

You can do that, but it doesn't give you any redundancy. See above.
For what it's worth, I -believe- that SWAP to a file on any RAID
filesystem is safe, but I don't actually know the code very well. If
you want to be safe with swap on RAID, upgrade to the 2.4.x kernels.
