Hello,

Would a reciprocal link exchange module per node be possible with this module?

I am thinking along the lines of
http:/www.linkex.dk
very nice link exchange module I use to exchange links for SEO and traffic for my site.

Basically, what I see is that at the bottom of each node, there would be a block where webmasters can add the links they wish to see, the page where they placed my link to the node. When he presses submit, his page is checked if he already has my lnk up, if yes, his link is posted.

linkex.dk does not count traffic but with Drupal the options are limitless, so perhaps this could be enhanced with displaying only the top 5 referrers per node etc.

There is a module already in place for reciprocal stuff but it seems it cannot be attached individually to nodes as I understand:
http://drupal.org/project/node_link

Reciprocal linking can also be achieved with the pingback module, but I dont think it checks links after a while and it is only for sites with pingback enabled:
http://drupal.org/project/pingback

Another one worth mentioning was toplist
http://drupal.org/project/toplist
but it seems abandoned as well :)

There was another project aimed at creating link directories but it seems abandoned:
http://drupal.org/project/janode

Then there is another nice module which formulates required links nicely per node:
http://drupal.org/project/link_to_us

All these combined would be a killer :P

I also replied to a feature request with these words at weblinks module here
http://drupal.org/node/292741#comment-1181870
to see which project is more receptive for this.
