If you have a host that you don't kill then you can target other things "as desired" (anthropomorphising). A biological "gunship". Ebola is a reasonable example. Avian flu another. SARS another. (Each example imperfect but all OK). But if you want to kill everything and still move around without using a gunship/bomber you need to separate the infectiousness from the payload delivery, have a long incubation period, make your infectious stage absolutely inobvious and have your delivery system reinvent itself regularly. All of which is what HIV does. It's only 'weaknesses' are a low degree of infectiousness and a reasonably rapid payload to help stamp out response once it starts delivering. We are, both incidentally, and almost certainly purposefully as well in any number of laboratories, helping nature produce such a 'weapon'. Stay tuned :-). >>...

There are no GM testing requirements that nature can't fit a barn door through (to badly mix metaphors). An utterly vital component in any protection/testing system is a belief by those involved that the protection system that they are part of is important and necessary. Few believe this. So the system is dead in the water. (Must be a year for bad metaphors). GM containment procedures in any number of high risk facilites are to varying extents constructively disregarded by staff. You may not ask me how I know, alas. Any sort of containment measures in field level activites simply cannot work - even if they are believed in by those involved, which they are not. Doom, doom ... !!! :-) Was the Balrog a GM product? RM -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
