zip library

Does anyone have any experience using a zip library like #zip with Unity iPhone. I currently am using an ASCII file, transferred over the web using WWW to rebuild model meshes, material etc., in my application. It works great, but the download times can be a bit of a pain. Those same ASCII files zip up to about 10% of their “native” size, so I’d like to zip them, transfer them using WWW then unzip them in the application.

I’ve also started reading into serialization which would be a more clean way for me to transfer objects, but won’t necessarily have the compression I need.

Any input is greatly appreciated.

no experience with them, but generally: the library must be .NET 1.1 to work on Unity iPhone at all at the time.
