Which busses (including system busses, I/O busses, and whathaveyou)
support hot patching?  That is, which provide the ability to add or remove a
card/peripheral/etc while the system is working, without causing a
disastrous effect to the system or data integrity?

I'm particularly interested in the current crop of popular system busses
(eg, MCA, MCA-2, ISA, EISA, S-Bus, DEC's many busses, FutureBus, VME, etc)
and I/O connections (SCSI, SCSI-2, IPI, DEC's many, TurboChannel, etc).

If you email, I will summarize.  Thanks.
