Both USB and SCSI have the device-to-device capability written into
some specs, but it's rarely implemented. ("USB on the go").
Which reminds me of a comment I saw somewhere about the possibility
of having
a SCSI bus with more than one host adapter on it. Is that even
possible?
Absolutely...SCSI is a (mostly) peer-to-peer bus. You can easily
set up multiple "masters" ("initiators" in SCSI parlance) on a SCSI
bus if the hardware implements the spec in a reasonable way and the
OS' drivers can do something useful with the capability.
Communication between host adapters is also possible; I'm sure
I've even heard of "IP over SCSI" having been implemented.
