Okay, I've pushed a change to master that adds two functions
`org-wl-open-nntp' and `org-gnus-open-nntp' to open nntp: links with
WL or Gnus, respectively.

You have to register one of the functions as link handler, e.g.

,----
| (org-add-link-type "nntp" 'org-gnus-open-nntp)
`----

nntp: links have the form:

nntp://server/group[/article]

Where SERVER is the nntp server, GROUP is the group, and ARTICLE is
the article number.

Limitations: Dunno how to supply login information in Gnus.  Thus,
opening a link like

nntp://user@server/group

will drop the "user" part and fall back to nntp://server/group.

Support for news: links is a little bit tricky: They have the format

news:[//server/][group|message-id]

Where GROUP can contain wild-cards (meaning: List all groups that
match) and MESSAGE-ID appears without a group (meaning: search for the
message with this id on the server).  And SERVER is optional.

The next step would be to supersede the customization variable
`org-gnus-prefer-weblinks' by `org-gnus-prefered-usenet-link-type'
which can be one of:

'http -- create web link to gmane or google
'nntp -- create nntp: link
