Providing location transparency for accessing instance variables
- Every access to an instance variable should test if the object is
local or remote.
- If the object is local, access the instance variable as in a non
distributed system.
- If the object is remote, send a message to the remote process asking
for the access, and wait (patiently) for the answer.
- The runtime must provide one thread to serve remote
accesses to local instance variables.
