Download/Upload gameObjects Unity 3d

Hi everyone,

I got question regards weather it is possibility for uploading and downloading 3D models from the application ??? What I want is to use new model when ever I request it, first now I,m able to list the amount of elements from the server,
now is how to download it into the application, It could be even better If I am able to download the prefab together with associated model??? If that is possibility then unity and you guys are rocking.

Anyone knows anything about it???

Regards,

Sam.

I also need help about this.
