IGRP is a 28 year old routing protocol from the stone ages, no wonder it was retired. EIGRP is a bit more modern ;-)
Cisco won't be discontinuing EIGRP anytime soon; it's the preferred routing protocol for building DMVPNs and Cisco DMVPN is a very widely used technology. Cisco definitely pushes EIGRP for building DMVPNs as it works better than anything currently available. The best way for OpenBSD to take hold in this area would be to implement NHRP (RFC 2332) and allow users to build DMVPNs using "nhrpd" and bgpd. BGP is not quite as good as EIGRP for DMVPNs, but it's a lot more scalable than OSPF.
