SARS sequence

The team that did the break-neck sequencing of the (probable?) SARS coronavirus is talking about some preliminary analysis that they've done. Good news/bad news: it doesn't look much like other coronaviruses. Bad because it means we're starting from the back tee in terms of treatment, good because it's not like we have great treatments for the coronaviruses we know a lot about (frex, the common cold).

By the way, I said '(probable?)' above because I haven't really been keeping up with the research linking this virus to the syndrome -- does anybody know how that's looking? Any chance that this isn't the causitive agent, or that it requires a co-factor, or anything?
