Just want to give an update on this matter. If the servers are placed in the new data centre (Number 8), virtual or shared ip address are no longer possible. This is only possible in their other data centres.

Just letting you know so that others don't make the mistake I made, and just assume it will work. (I really must learn to make less assumtions!)

Having said that, they are trying to find room in one of the other data centres for me now. I really really hope they do :-) and I just wanted to say thank you for suggesting to talk to the datacentre guys directly. They are certainly A LOT more helpful!!
