There is no 'or' involved. AppleTalk is the protocol for sending data, and AppleShare is a program to control who and what 'sees' what. You need both. LocalTalk (serial port to serial port) is the physical connection between Macs. LocalTalk was invented by Apple to allow several Macs to connect to a single (very expensive) LaserWriter, extended to allow Macs to connect to each other. It's part of the System, and it just 'is'. All you can do is substitute it with Ethernet in the Network Software control panel if that is installed and visible to you. The older Network control panel is invisible when it is installed, and works its magic unbeknownst to its user except by the results of its working.
Although you must set up the Performer as a server, the act of filesharing is controlled entirely from the Plus. In all probability you will see nothing in the Chooser window of the Performa. In the Chooser window of the client Plus you will see the name of the Performa, and the software will mount a representative network icon of the Performa's HDD on the desktop of the Plus. You must set up the Performa to share its files. You cannot invert the process (ie, make the Plus into the server) under 6.0.8 because there is no FileSharing control panel. Try the setup again with these immutable considerations in mind. You haven't mentioned the System/OS on the Performa. This won't change what you have to do, but what you see on the Performa will be displayed differently depending as the Performa has System 7 or OS 8 or 9.
Embroider this motto on your handkerchief and hang that on the wall: 'Never be defeated by an inanimate object'. If the setup is not working, you may have to consider that the fault lies in the Performa, and to fix that.

PS Loved the audio in your QuickTime production, but there was no video (iMac CRT 500, OS 10.4.10, QuickTime 7.2 with Pro key).
