Shouldn't be a problem if you're using static pages. I'd guess that most people pinning the resources are using poorly coded scripts/inefficient DB queries, etc...
Plus, you can use your space here for storage which is usually a fine-print no-no with most hosts that offer large amounts of space.
The main reason that it works out is because most of us use less than 1% of what we're paying for, so it's not like a few people that actually use it are going to bankrupt them.
On the other hand, a smaller host trying to compete on price might not be able to back it up and start searching for a reason to cut you off. There have been recent complaints of Bluehost lowering the CPU limits on their cheap plan, so that you'll upgrade to the more expensive one -- but at DH, it's the same whether you go with any of the plans.
Needless to say, the TOS still applies... so if the large files are illegal in anyway (kiddie porn, copyright issues, etc...), CPU resources won't be the reason you're cut off.
