Actually nearly real time distribution (not older then 10 minutes) of IRR
data is already available since November last year (I wrote the code
myself ;-)). The software has certainly still some rough edges and was
published at the same time. It works now quite reliable for some time.

You can contact me at <ripe-dbm at> if you need more information or
want to have such a mirror running at your site.

Kind regards,
