I'm only playing Dick Advocaat here, but is Static IP as opposed to Dynamic IP such a big deal-breaker to the average, unawares punter ?? I speak to a helluva lot of EU's, and I'd openly say that probably 95% of them won't even know what it is.
Don't get me wrong, I like Zen. On the very few occasions I've to co-op with their tech guys on a fault, they've been helpful and knowledgeable. A big plus in my book, rather than have to go through the in's and out's of a gnats fart like you do with some ISP's 'Tech people'. Plus, they are a local business to me, living where I do, so I wish them all the best on that level too.
