I don't claim to be an expert on networks, including MacJANET. I am
basically going by what several people told me about multilaunch
capabilities under networks.  MacJANET certainly doesn't solve all
network problems.  For example, Switcher does not work with MacJANET
network volumes since the software is read-only and Switcher doesn't
like that. I'm sure there are other programs that don't work especially
if they try to modify themselves.  I have tried the following software
under MacJANET (without any modifications) without problems:

        MacWrite
        MacPaint
        Word
        SuperPaint
        MacDraw
        Reflex
        Works
        Statview 512+
        CricketGraph
        Pagemaker
        ReadySetGo
	RedRyder
	MacLinkPlus

Hypercard doesn't work under MacJANET if loaded from a read-only volume,
which is well know for Hypercard.

We like MacJANET because it provides a pretty secure environment for our
software. In the next version due shortly it will also limit the number
of copies of a program in use, allowing us to buy fewer copies and restrict
the usage. It will also have an encryption facility to make software
pirary very difficult.  MacJANET has its own types of problems, but
we're happy with it.
