Large client corps/orgs with a few thousand each Linux, MS, Oracle servers are not a lot faster. Dynamic online tz updates are as desirable for their stability impact as Windows updates ;^>

Dynamic online updates are really intended to allow personal clients to accept a certain downside risk and not have to think about updates. Most IT people and groups prefer stability, and while they may automatically download updates, will test and evaluate the risk before applying. Don't see a web source delta distro solving any problems or adding much value, unless vendors see enough downstream support savings to build the download and update process for the binary data, which they have not done yet. Someone may decide to build an app for that.

Take care. Thanks, Brian Inglis
