This is a pertinent thread and I also have some questions:

1) How do we know that Transceiver Rx signal levels are <1.1 Vp-p? Can we infer that they will be safe if connected to other Altera Transceiver Tx outputs or must they be actually measured at the device balls?

2) What does it mean to drive to VCCIO if powered down? Does this mean the local VCCIO (which will also be powered down by definition) or the remote active VCCIO?

3) What do the '-' cases mean? Do these mean that these cases are not allowed or can't happen???
