VeriSign Naming and Directory Services (VNDS) currently generates new versions of the .com/.net zones files twice per day. VNDS is scheduled to deploy on September 8, 2004 a new feature that will enable VNDS to update the .com/.net zones more frequently to reflect the registration activity of the .com/.net registrars in near real time. After the rapid DNS update is implemented, the elapsed time from registrars' add or change operations to the visibility of those adds or changes in all 13 .com/.net authoritative name servers is expected to average less than five minutes. The rapid update process will batch domain name adds and domain name changes every few seconds. The serial number in the .com/.net zones' SOA records will increase with each batch of changes applied. As described in a message to the NANOG list in January [1], these serial numbers are now based on UTC time encoded as the number of seconds since the UNIX epoch (00:00:00 GMT, 1 January 1970).
Rapid Updates to .com/.net Zones Faq:

The very next paragraph after Brett's quoting above is:
VNDS will continue to publish .com/.net zone files twice per day as part of the TLD Zone File Access Program. [2] These zone files will continue to reflect the state of the .com/.net registry database at the moment zone generation begins.
Am I reading this correctly? They'll still only publish the updated files twice a day? If so, what's the benefit? Someone want to fill in the blanks here?
In the past one had to wait at least 48 hours for full propagation.

They're only publishing the zone file twice a day as part of the "TLD Zone File Access Program". This I think lets you download the zone file for your own use. This is separate to pushing zone updates onto the live DNS servers which they will be doing every 5 minutes or so.
Secondly, it won't directly affect DNS propagation when you are, for example, changing hosting companies or servers - that depends on the TTL (time-to-live) - it only helps brand new domain names appear more quickly on the root-level DNS servers, allowing them to propagate out more quickly.
The world is moving faster in all ways, Google will have to respond sooner or later with faster inclusions in it's index or they will suffer the same fact as the SE leaders of the past, (remember when Altavista and Webcrawler were the Top Dogs of search ;-) )
