Zabbix Website should have a exchange platform for zabbix templates/external checks

Exchanging zabbix templates or external check scripts is currently a real pain - the wiki page contains lots of bad and outdated templates.
(see: http://www.zabbix.com/wiki/templates/start)

From my point of view zabbix will not elevate to a higher level of distribution without this

The zabbix website should have a area to exchange zabbix templates and external check scripts in a comparable way of nagios-exchange.
(example: http://exchange.nagios.org/index.php?option=com_mtree&task=search&Itemid=74&searchword=mysql)

From my point of view, that website should provide the following features:

• users should be capable to add their templates/external check scripts by their own
  (name, description, categories, download url, sourcecode repository, ...)
• link to recent templates/external check scripts in sourcecode repositories
  (i.e. github, self hosted svn and git repositories, ...)
• link to detailed documentation in sourcecode repositories
• searching for suitable templates
  (full text search, tags, ...)
• users should be capable to rate and comment
  (to help users to find out details about the quality of the templates/external check scripts)
