+@item share=[allow-exclusive|force-shared|ignore]

+Set display sharing policy. 'allow-exclusive' allows clients to ask
+for exclusive access. As suggested by the rfb spec this is
+implemented by dropping other connections. Connecting multiple
+clients in parallel requires all clients asking for a shared session
+(vncviewer: -shared switch). This is the default. 'force-shared'
+disables exclusive client access. Useful for shared desktop sessions,
+where you don't want someone forgetting specify -shared disconnect
+everybody else. 'ignore' completely ignores the shared flag and
+allows everybody connect unconditionally. Doesn't conform to the rfb
+spec but is traditional qemu behavior.
