The Hamachi VPN software hasn't been abandoned but continues to be made available under LogMeIn brand still using the 5.0.0.0/8 netblock for it's addresses.<br /><a href="https://secure.logmein.com/UK/products/hamachi2/" rel="nofollow">https://secure.logmein.com/UK/products/hamachi2/</a><br /><br />Another similar product using the addresses in the same block is Comodo EasyVPN<br /><a href="http://www.comodo.com/home/email-security/vpn-access.php" rel="nofollow">http://www.comodo.com/home/email-security/vpn-access.php</a><br /><br />In both cases I've tried asking the companies what they intend to do now that the 5.0.0.0/8 block has been assigned to RIPE but I've not had any official reply so far.
