The problem with compression is, it's everywhere. Sending a jpeg, over compressed http(s), throught a compressed and encrypted VPN is too much compression. Then the client may save the jpeg to a local compressed NTFS cache... This is just wasted performance, plus compressors are a common place for bugs, so this is also a security issue. Just stop adding compression to everything and think about it first, and then Mobile phones and modem lines may very well be an exception.
