The Opteq implements selective compression between ANY 2 POINTS in a data stream that have an Opteq unit. It doesn’t matter what’s in between, only that the data that is compressed also passes through the second unit so it can be decompressed back to its original content before it reaches the target device. If it seems pretty simple, it’s because it is. If you have an Opteq system at your office and you have one at home, you can compress all of the traffic from your office network to your home PC transparently. So if you have a 256kbs connection, it will appear to be 2-3x faster, in most cases.
