You can find it yourself if you evaluate the following.
Squeakland 3.8-05 of 1 September 2005 update 546
so the image seems to be of 3.8 family. I guess that the source of the updates is also different than "normal" Squeak images (this is related to the `546' update number).

no, "Normal" Squeak, Squeak plugin as well as Croquet share the same virtual machine (at least I do not have problems running those different images upon the same virtual machine).

`npsqueak.so' is a plugin to firefox, mozilla etc. I am not aware of all the details (how things are mutually called and under what circumstances) but the code of `npsqueak.so' is able to check various things (where is the virtual machine binary, where is the plugin-image and if everything is all right, it `exec'-utes the virtual machine with proper parameters
- it tells it what image to use
- it tells it what X-window ID to use as a main window of Squeak world
and such things. `npsqueak.so' itself is not a virtual machine. It is but a glue.

Since in both cases the same vm is used, there is no conflict or problem with overwriting.
