This shouldn't be a problem from what I understand: "real" ground is just tied off to a rod buried in your backyard, but it's also bonded to neutral at the switchboard anyway.

Depends on the country. Over here protective earth is entirely separate from neutral, and there's a separate earth stake for each consumer. This is the TT system.
