"Resource discovery" is identified as a problem. And a possible solution is proposed: By the way, it would be easy in principle for a third party to run over these trees and make indexes of what they find. Its just that noone has done it as far as I know because there isn't yet an indexer which runs over the web directly. Now, if there was only some money in that ...
In the long term, when there is a really large mass of data out there, with deep interconnections, then there is some really exciting work to be done on automatic algorithms to make multi-level searches.

"The cost [...] has been evaluated, taking into account realistic labor prices in different countries. The total cost is X (with a western equivalent value of Y)" [where Y>X]
