Well before we had JEP-0115 clients that supported disco and wanted to
find out what other clients supported would send the disco request to any
people as they become available (i.e. receive an available presence stanza
from them), but this was a bit bandwidth intensive and could cause a bit of
a flood of requests when a user logged on, so JEP-0115 was developed so that
you could help avoid this flood of requests everytime because it would tell
other clients in that first presence stanza they receive from you what your
capabilities are so they dont need to necessarily flood you with disco
requests as you have already told them what you support and can just use 
their cache of the disco requests that link with the caps that you 
published, this avoids them rerequesting disco infos everytime you log in.

Yup its pretty simple and entirely follows standard protocols the way they
are intended to be used which is cool.
