Sorry about that. I'll inline it here.

Using the CrawlableDataset framework for the aggregation scanning is on our 
list of things to do. However, it isn't very high on our list at the moment. 
So, I'm not sure how soon we will be able to get to it. If you guys want to 
take a look at it, we would be happy to help as we can. Otherwise, we'll have 
to think a bit about when we might work on this.

I'm not sure I can say much about what lies ahead in terms of working on the 
CrawlableDataset framework. Mainly because I'm not sure what you guys are 
planning. I suggested a CrawlableDataset implementation to Bas' because you 
wanted to catalog OPeNDAP collections. Besides aggregation, do you have other 
plans in terms of the TDS, cataloging, and serving data?
