Ok, so not so simple. =) I'm not familiar with the layout of PCH's data (I did find some .gz files, so I presume that's the data that's gathered on a daily basis), but if I was, I would have to take the divide-and-conquer approach for a certain AS to find out when a block was first announced. I'm guessing that I would have to do the hard work. Perhaps Renesys is already doing this? (but for a fee).

By that, I mean that they could be run daily, and specific results emailed to people who were interested in following the allocation patterns for specific organizations, any time there was a match. -Bill
