Krups B100

I just got a Krups B100 as a gift, it is a fridge tap machine for the counter. I do not usually drink Heineken or anything that is available in those small keg things. I was wondering if anyone knows of a way to get your homebrew into one of those kegs or of there is a homebrew version to use this thing with.

if you google Krups B100 you can see what it is, they run about 140 bucks. It was a gift so I would like to find a use for it.

Here is something that might help
