As I mentioned a while back I'm using a pair of ReadyNAS NV+ RAID systems as my on-site data store and off-site backup. These are both working well and I'm pleased with the solution. After a few hickups and delays due to the Netgear takeover of Infrant it seems that the firmware is developing nicely again and the latest thing that I've discovered is that you can now develop and deploy your own code to the devices (if you're brave enough!). See here for details. Given that I'd need to purchase a third unit as a development and testing box and given that I'm currently really busy with client work I don't expect that I'll actually be doing any development on the NAS in the near future but, hopefully, someone may now make it possible to run a CVS server on it...
