there are actually a number of viruses with this feature: HIV, hepatitis A virus, HTLV-1 and -2 and in humans, SIV and STLV in monkeys, FIV in cats, Visna in sheep, and MLV in mice, to name a few.

HIV is not characterized by a fast replication. On the contrary, there is a long, latent phase of the HIV infection when little or no replication occurs.

Sure, but this is by no means unique for HIV. What you are talking about is called antigenic variation, and this variety is also the way of life for the influenza virus, for example.

Again, this is nothing unique for HIV. Generally, antiviral drugs don't really kill of the virus. Instead, they inhibit certain steps in the viral replication and thus help the cellular immune system to get rid of the virus.

But, even if any of these features would be unique for HIV it wouldn't make it more probable that the virus could be man-made. It seems like many people believe that just because a pathogen (bacteria, viruses, parasites etc.) has some unique features, there is something mysterious about it. However, many pathogens (not to say all) has unique features that make them more invasive or more resistant to our immune system: the Mycoplasma bacteria lack a cell wall and can't be fought with antibiotics such as penicillins, the Trypanosoma brucei protozoa ( the agent causing sleeping sickness) interact with the neurons in the brain to make them produce more of a substance that the parasite can use for its own growth, the Herpes simplex virus can rest latent in immunoprivilieged tissue (in this case neurological tissue), etc etc. These pathogens can all be called "smart little things"; however, there is no doubt that they have existed for thousands of years...
