Actually, while HyperCard works that way, Revolution lets multiple users 
open a stack and write to it. If two people have the stack open at the 
same time, either one can overwrite the other's changes. Record locking 
has to be scripted; often accomplished by writing a small text file to 
disk that tracks usage.
