As I said in a previous post, our business objects don't reference each 
other via there OID, so no it's not important for me. And yes the OPF 
frameworks takes care of the nitty gritty stuff.

For those not using the tools I use, might not be so luck. In example... 
Using the standard DB components in Delphi or Lazarus and using 
Master/Details grids and tables, you need to save the master record 
first, find out the unique identifier of the master record, include that 
in the SQL for the detail records.

In the this example you need a extra round trip to the database if your 
application can't generate a unique identifier itself. GUID's make this 
a no brainer. :)
