Sharing directories on a domestic LAN

[il barbi]

I have a domestic LAN made of 2 PCs connected by an Ethernet crosscable, now
I'd like to read and modify all files of PC2 from PC1 and viceversa but I'm
puzzled on how to set the sharing options - it seems to me that it is
possible 1) to share and a directory on PC1 among all users of PC1 and 2) to
share a directory on PC1 among ALL users "in the net". Now I'd like to share
a directory of PC1 only with users of PC2 and no more - is there some way to
distinguish users of my domestic LAN from all others?
This is because I'd like to share the entire the whole C: among PC1 and PC2
but I read that this is highly risky

All objects of the C: drive are already shared (via a hidden share)
which you can access as long as the person on the second computer
knows the password of an account on the machine sharing the files.
(Access these files by entering \\computername\c$ where computername
is the sharing computer's NetBIOS name or IP address)

Windows does not care whether a user comes from PC1
or PC2. It only pays attention to the user name and the
password.

Here is a simple way to implement your scheme:

1. Create a number of accounts on both PCs: One for Luigi,
one for Teresa, one for Gianni. Make sure the passwords
are the same on both PCs.
2. Create a share called "DriveC" on PC1. It should point at C:\.
3. Set the permissions for this share so that only Luigi, Teresa
and Gianni have access to it.
4. Do the same thing to PC2.

You will now find that Luigi, Teresa and Gianni are the only
users who can access the share called "DriveC", unless you
have some restrictive NTFS permissions.
