what is the meaning of the ORBid in CORBA_ORB_Init()of orbit2

[Gilbert Fang <gilbert fang sun com>]

Hi, experts
  The document said that ORBid is a name presenting  a ORB
implementation.  Then what is the real meaning of it when writing codes?

  If I write a servant  using  "example" as a ORBid, then write a client
using "local-orb" as a ORBid, can it work? Then does that mean I have
two orbs even I only installed on orbit2 in my pc (rh8.0)?

 I am really confused?
