Smallpox/cowpox, HIV/SIV, Poliovirus/rhinovirus ... you have to actually look at the reality.

Rhabdos are insect viruses and they get on with their hosts quite well. See <a href="http://www.ncbi.nlm.nih.gov/pubmed/17550883?ordinalpos=5&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum" rel="nofollow">Drosophila sigma virus</a> for an exquisite example of this well-adapted relationship. Nah. Rhabdos are insect viruses and they get on with their hosts quite well.

See Drosophila sigma virus for an exquisite example of this well-adapted relationship.

Maybe we can still say that in nature, virus-host co-evolution always tends toward decreased pathogenicity?

To that I say:
Rabies.

Funny you should bring up Myxoma Virus. I was just reminded the other day by a colleague of the fact that Myxoma is avirulent in its natural host, the South American rabbit <i>Sylvilogus brasiliensis</i> and only lethal to the European rabbit. (see http://www.ncbi.nlm.nih.gov/pubmed/12297325?ordinalpos=3&itool=EntrezSystem2.PEntrez.Pubmed.Pubmed_ResultsPanel.Pubmed_RVDocSum) I'm not sure it's known exactly why this is, and I'm also having trouble deciding whether it supports your argument or not...
