Get a fresh Oort (or wait for 5.10).  "nntp" is correct (and recommend
by RFC), but wasn't implemented in Gnus.

For me, it's just the other way round (sometimes): When people post
links like <URL:http://article.gmane.org/gmane.discuss:3191> I'd like
Gnus to behave as if there was a
<URL:news://news.gmane.org/gmane.discuss/3191> link instead.  Then I
don't have to switch to the browser.

Same for Google-MID-URLs:
<URL:http://groups.google.com/groups?hl=en&rnum=1&
threadm=87bs6teihl%2Efsf%40amaterasu%2Esrvr%2Enix> should behave as
<news:87bs6teihl.fsf@amaterasu.srvr.nix>.

I already wrote some HTTP->NNTP URL conversion (not yet committed):

,----[ C-h v gnus-button-prefer-nntp RET ]
| gnus-button-prefer-nntp's value is nil
| 
| Documentation:
| Try to convert Google or Gmane HTTP URLs to corresponding NNTP URLs.
| 
| If `nil', no conversion will be done.  If `t', all URLs will be
| converted.  If `ask', query the user what do do.
| 
| You can customize this variable.

Hey, your using Gnus, it should be done in Lisp!  Maybe I can
implement the other way round too, i.e.:

  (news|nntp)://news.gmane.org/gmane.discuss/3191 -->
  http://article.gmane.org/gmane.discuss/3191
and
  news:some@foo.bar.invalid -->
  http://groups.google.com/groups?hl=en&rnum=1&threadm=some@foo.bar.invalid

Does this make sense?

Bye, Reiner.

PS: Does (or could) Gmane convert...

I'm not sure.  Let's test it:
