226w ago - Here is a video of
PS3 Proxy Server (alternate
PS3Proxy) being used with PS3 Firmware 2.60.
Note: It is believed that once you download the
PSN PKG file you can see it in the XMB and still (as always) have to
install it.
The video does not show that, most likely because the installation would fail generating an error as it has since around the 2.4 PS3 Firmware Update. This is likely why the bubble is still around it when it's shown in the PS3 XMB.
However, the video does show the downloading of a file via PS Proxy. Feel free to comment below if anyone experiments with this further!

I can't confirm that but as I remember PS3 Proxy does not support https traffic which could be used to download some kind of activation file after downloading the demo file.
