skill code for working with internal entities via IPC

Is it possible to take an internal object, write it to a string, store it in an internal program, then re-use that value in
a Skill program?

For example, if I do this:
rc = ddGetObj( "00test1" )    
dd:0xacb0168

to get a library reference stored in variable rc, can I write the value of rc to a string and later recall that value (perhaps
storing it in a completely different variable) to access the same library?  In other words, what I would like to do is
something like this:

myIPCwrite( rc )        to save the value of rc to an extneral process
...            
lib1 = myIPCread()    to recall it
