How about temporary memory table just for the task of storing your objects.
You initialization code for particular connection
Attach ':memory:' as MyObjectStorage
Create table MyObjectStorage.[objects] (Name Text, Ptr Text)
Your code for inserting an object
Insert into MyObjectStorage.[objects] (Name, Ptr) VALUES ('obj1',
'0x12345678')
This code will query the pointer
select Ptr from MyObjectStorage.[objects] where Name='obj1'
The only convention rule here will be the name of the attached db so no
other databases (or instances of the same storage) should use this name.
