Currently I am with Zen on their ZenADSL Home 2000. They have introduced usage restrictions on this type of account and told people to move to their Zen Office Max 8Mb if they want unrestricted usage. This is very expensive @
I maybe wrong, Nildram are now owned by Pipex. If their home service is anything to go by you might be restricted on their buisness product too. But as i said this is just a guess.
