metacard and language tools

[sbancher at utm.utoronto.ca]

I was wondering if it is possible with Metacard to open in the background 
another application, paste in a new document the content of a specific field, 
do a spellcheck or word count and import the results in metacard.

To be more specific,  I have created a language testing program which also 
include a composition. Once the student write the composition, my program will 
analyze it and report some features of that composition in a .txt files.

I would like to combine my program with another commercially available software 
(Errata Corrige, an Italian language tool).  The idea is to have metacard paste 
the composition in a new document in Errata Corrige and ask it to choose the 
menu item "statistics". When asked for statistics, Errata Corrige would produce 
a graph (image), which I would like to import in metacard or directly in 
the .txt file or .rtf file.

Is something like this at all possible?  If so, does anyone have any 
suggestions?

Many thanks,

Salvatore
