	I am trying to impliment a networked application using HyperCard.
I have found out that if HyperCard can see a path to a mounted disk on
a network it will use it.  I have a MicroVax (Ultrix) file system
mounted on a PC using PC-NFS and in turn that file system mounted to the
TOPS Network, it really works!.  I also found out that if you lock a stack
(file) from "GET INFO" everyone on the network can "view" the stack.

Question: Is there a way to lock/unlock a file from HyperCard?

Another unrelated question: If the memory is increased from 1Mb to
2.5Mb in a Plus how much speed increase will I experience using
HyperCard?  Also what effects would "RAM cache" make and what would
be a optimum value.

Thanks
