Which virus scanner vendors support scanning NSS volumes on OES servers?

The OES partners page is ambiguous
Open Enterprise Server | Partners

It lists five vendors that "work seamlessly" with OES. But on further inspection most of the vendors don't appear to support or aren't committed to OES11 (I'm guessing they mean SLES11). Does it matter that they don't support OES11 (SLES11) if they support OES2? I would assume that support of OES2 implies that they scan NSS, is that the case?

Best regards,
