Decompressing ZIP

Hi,
i’m working on a little project involving drawing strokes and stroke animations in an HTML5 canvas object in a website which are then stored in an mySQL db.
using GML(XML) for storing stroke data turned out to create too large files, so I implemented clientside ZIP compression prior to uploading the data.
Now I’m curious if there is a way to decompress it in vvvv.

thanx!

two ideas:

…and if you managed to create a module or a plugin don’t fear to share it it with us :)
