Well, you took my word for it anyway. A third party router that supports DDNS is not hindered by the SH in modem mode.
BTW the link and search did work for me. The search would have brought you:

Hi
Thanks for the comments - sorry to have been a few days in approving comments & responding ... been maxed out!
Andrew - This is a new one on me. Can you please report it on the Help & Support forums (http://community.virginmedia.com/) with some details and the community team will pick it up asap.
Mr Barton - Don't have a firm date yet, but it's being worked on right now and we'll publish details on the Help & Support forums as soon as we have some news (as per previous responses).
John - Way over my head sorry, but I checked in with the expert:
"Your Synology NAS box should work fine with our SuperHub but may require a little bit of port forwarding and configuration for it. Does your current router support Dyndns login via its configuration pages? Our Hub doesn't directly support the Dyndns login so it would just be a case of checking every now and then to ensure your IP hasn't been changed and updating your Dyndns account accordingly if it has. Other then that just setup the required ports to forward and it should work fine
