IPAM software that integrates with RIPE

Hi, ripe-list :) I've been asked (by a telecoms company) to research the options related to managing IP blocks and integrating with RIPE. Part of this is to see if there is some existing software out there that can be put to use. So my question is: Does anyone know of any good existing solutions for IP Address Management that integrates with RIPE out of the box or that can easily be adapted to do so? The only IPAM solution I have found so far that states integration with "Internet Registries" is BT Diamond IP's IPControl. If someone has any experiences with that piece of software, I'd also love to hear about it. Regards, Roger Kind Kristiansen
