Any one know if Atlantic Broadband is going to offer access to this. I've been a long time HBO subscriber and would really like to take advantage of this

I don't know, but I have a suggestion (because it's easier to kibitz than offer a real answer).

Call or contact them directly and ask. The more people that ask the more likely they are to consider doing so. Especially if you mention how pleased you, a loyal customer, would be.

Called them and they don't currently support it but said others have been asking for it as well. We'll see!
