Great idea ! One question through : is the image loaded with file i/o
primitives, or does it use "private" code ?

Well, I thought that it should start with a small image that contains
general-purpose and widley-known classes (collections, magnitudes,
numbers...). It would have to implement also "IActiveScriptParse" (not sure
it's the exact name for it) to be able to receive scripts as strings from
the host (the browser for instance). When squeak is called to parse a
script, it would store it as a block, somewhere (I don't know where
exaclty), and execute it when asked to. No need to trick the image here I
guess :-) However, I thought that such a facility would exist, as I have
seen it in other smalltalk environment. Can't it be done with squeak ?
Moreover, the "parser" interface allows retrieval of the PARAM and / or DATA
attributes of an OBJECT. Maybe one could reach an image with the OBJECT tag,
and then launch one's scripts within it...

Anyway, thank you for your advice about COM use, you seem to know it much
more than I do ! :-)
