Yes.

Presumably yes. But if say, a resistor was connected in the ground feed
a few more possibilities arise dependent on the position of the ground
terminal.

If the cage was ungrounded and the secondary return grounded, a voltage
would exist between the cage and ground which -if sufficiently large- would
allow.
tubes to be lit from contact with or proximity to the cage exterior.

If the cage was grounded and the secondary return ungrounded, a voltage
would exist between secondary return and ground.
Tubes could then be lit from contact with ,or proximity to, the secondary
return lead.


I have not seen the new Philips bulbs yet.
  Do you referring to "induction" lamps that use a coil to excite the gas
without electrodes, or the more common compact fluorescent lamps (CFLs) that
use a half-bridge inverter and series-resonant tuned circuit to produce the
high voltage needed to start the tube, only I understand that Vladimiro
Mazilli uses a similar circuit to the latter in his SSTCs.
