Ideally, you need a static IP address to run a web server, so you would have to find a way of dealing with Now only providing dynamic ones, which do tend to change, and change without warning.
You also might have a bit of a run-in with the T&Cs, about that sort of usage of Now Broadband.
Performance, over the asymmetric FTTC link, might flag a bit (understatement).
And I hope you would be skilled at keeping all the nasties at bay.
Much better to sign up with a commercial service designed for the purpose, which can be quite cheap if the volume is low.
Set a Payment PIN on your account so that no-one but you can buy memberships on it.
Check your bank accounts monthly for any other unexpected payments to Now.
That way you can at least nip them in the bud, while you and Now figure out whose fault they are.
