Update 2: Thar she blows. Comcast spokesman Charlie Douglas directs my attention to their updated network management website, which confirms the October 1 cap launch. From the website:
Measuring your caps by e-mails sent is a little lame (though increasingly common). That said, 250GB is a generous cap, particularly when compared to the 5-40GB caps being considered by companies like Time Warner Cable and Frontier. It's good that customers will no longer have to guess how much usage constitutes gluttony, and it's great to see that Comcast left the overage fee concept on the cutting room floor (for now). The site says that Comcast customers should see notification in their bills shortly.

Today, we're announcing that beginning on October 1, 2008, we will amend our Acceptable Use Policy (AUP) available at »www.comcast.net/terms/use/ and establish a specific monthly data usage threshold of 250 GB/month per account for all residential customers.

This is the same system we have in place today. The only difference is that we will now provide a limit by which a customer may be contacted. As part of our pre-existing policy, we will continue to contact the top users of our high-speed Internet service and ask them to curb their usage. If a customer uses more than 250 GB and is one of the top users of our service, he or she may be contacted by Comcast to notify them of excessive use. At that time, we'll tell them exactly how much data per month they had used. We know from experience the vast majority of customers we ask to curb usage do so voluntarily.

Sounds to me like some may not get any notice at all.


Also,
Contacting you a month and half after the "abuse" has occurred has been too late according to many posters in the forum.

So which is it?
Either they will or whether they may contact you...

What will happen if a customer exceeds 250 GB of data usage in a month?

The vast majority - more than 99% - of Comcast customers will not be impacted by a 250 GB monthly bandwidth or data usage threshold. If a customer exceeds more than 250 GB and is one of the heaviest data users who consume the most data on our high-speed Internet service, he or she may receive a call from Comcast's Customer Security Assurance ("CSA") group to notify them of excessive use. At that time, Comcast will tell the customer exactly how much data per month he or she had used.

If a customer surpasses 250 GB and is one of the top users of the service for a second time within a six-month timeframe, his or her service will be subject to termination for one year. After the one year period expires, the customer may resume service by subscribing to a service plan appropriate to his or her needs.

Will all customers who exceed 250 GB of data usage in a month be identified as excessive users?

Yes, Comcast is setting 250 GB as the residential data usage threshold for excessive use. Customers who exceed 250 GB and are among the top users of Comcast's high-speed Internet service may get contacted by Comcast about their excessive use.
