I think using ia virtual image would be the best here so it is also possible 
to run the tests on a different systems. Running it on the above hardware 
sounds like a good idea.

Not sure how good it is to use git as the stuff put there will be documents and 
images which are basically binary data

Yes it goes through the entire document. Also the different sheets are handled. 
There is one limitation at the moment for spreadsheed documents as only the 
first page of each sheet is takes into account. I will try to overcome this 
limitation. For words I plan to also support all kind of documents but I still 
have problems with gerating the images there.
