[44net] BGPed Gateway

Hi, I received a 44 net allocation and am successfully advertising it to the internet via my ISP. I have been reading on the AMPRNet Wiki about IPIP tunnelling and Startampr.  Are there best practices or anything else I need to be aware of before venturing into building the gateway? On a related note, I have been using OpenVPN to provide publicly routable /32 IP addresses to individual Windows PC.  I don’t see support for IPIP on Windows, are there any other tunnelling methods worth looking at, for Windows7 specifically, or is OpenVPN my best bet? Thanks, Adi VA3ADI
