This is also not implemented yet.

For case 1) above, you should certainly expand the current driver (although
again, this all depends on whether the ESX SOAP API supports this operation,
which I can't answer).

For case 2) above, it's a lot more tricky.  If you look at
src/interface_driver.c, that is one network interface driver that can enumerate
all of the physical devices on a host (using netcf as the backend).  *If* the
ESX SOAP API's provide something similar, then you possibly could write a new
network interface driver for ESX that used the SOAP API's on the backend.  This
would be a whole new interface driver, and may require new API's (although I'm
not sure about this, since I don't know the interface driver very well).
