The problem with doing this, is that you haven't specified the time frame of how long they want to archive it.

I'd probably just dump the data to tape, ideally using an application aware tool, but in this case, just getting copies of the VMDKs is probably enough.

Can't really beat tape for cost... esp if you want to be paranoid and make TWO copies to tape, so they you can shutoff the original filer as well to save on electricity and cooling costs.
Not sure why you hate tape, plain ole 'dump' from the filer console will do what you want. Esp if you dump each volume to it's own tape(s) to keep it easy to restore.
