Alan, thanks,
it seems convenient to move memory from Smalltalk to Smalltalk,
but i did not see any example using an ExternalAddress.
Since ExternalAddress are ByteArray with four bytes containing the address, 
i'am afraid it won't be interpreted as a pointer, but an array of 32bits...
Or maybe i am wrong?

Andreas, thanks
but then how do i gain pointer access to data through smalltalk oop?
Is there another way but writing a plugin?
If i must write a plugin, i suggest this kind of basic service being included 
in future FFI releases.
