A very nice feature of DNS is that it not only transports the information (serial number) but also the metainformation when to refetch the data. This means that the clamav nameserver control the TTL (time to live) of the data. A nice side effect of this is that it allows for a flexible _server_ based control of the DNS retry intervals of the clients. E.g. the virusdb people get a new signature/virus. While investigating the data they might consider to already lower the TTL so that the clients check the DNS more frequently. As soon as the new signature/virusdb is available the clients notice this rather fast. In addition by managing the TTL the server can control how hard it is hit when a new signature is available. Shorter TTL means less smoothing but better latency. IMHO using the DNS intelligently helps not only for the QoS but also the internet as a whole because it avoids unnecessary and unproductive load on all systems involved. Side note: Lets hope that no 1$107 gets the idea to patent such a mechanism as it just happend recently to us KDE people. (A KDE person had a UI idea and presented it on a KDE ml. KDE implemented this idea in the following months but MS took the idea, added the obvious and patented it :-(. MS even cites the KDE ml as the source of the initial idea.....)
