9    An important assumption underlying the Web and many other hypermedia
10    systems is that an identifier, if it is to be resolvable, must
11    include information about where to find the resource it identifies.
12    Berners-Lee [ref NameMyth] argues that identifying documents
13    by unique, completely random identifiers may be desirable,
14    as unlike for a URL, there is little reason for a random identifier
15    ever to be changed, but that it is not possible to resolve such names
16    on a global scale. However, recent development in peer-to-peer systems
17    has made scalable indexing systems possible, rendering this assumption
18    obsolete. This, we believe, is the most important result of
19    peer-to-peer research with regard to hypermedia.
