Dear Penguin,

Could you provide citations regarding virus of the archaea?  I have been
working with archaea, addressing ecological questions, and have so far
missed all of these findings.

If, by "extremophile phage," we refer to a phage capable of existing
and remianing infectious under extreme comditions, then these are not
rare.  If we are instead talking about a phage capable of expression
and replication under extreme circumstances (and thus parasitic of
extremophilic bacteria,) then that is a different issue.

Just thought I would write that explicitly, in case any two people on
the thread had differing interpretations.
