Americans should hire remote sysadmins.

The big thing for me is not the time difference per se, but the lack of integration with the business objectives and the other team members. It's the fact that the operations/infrastructure/scaling side is critical to the success of most startups (ie. Twitter).
If a good ops guy knows he needs 4 extra large instances of some cloud host, spread across different regions, he needs to work with the developers to make sure they are developing their software correctly for the architecture. And monitor the growth of the application, usage, etc to ensure it scales correctly.
I would think the majority of startups would want their sysadmin to be tightly integrated into the business and not just "some guy" who keeps the rented cloud servers running.
My main point is that it's possible to get a specialist for less than a Valley-focussed startup might realise, not that you should just hire 'some guy' who is detached from your team. If your remote workers aren't integrated into your business then you're doing it wrong (and don't think that you absolutely need everyone in the same room: look at GitHub, who do superb work with a distributed team).
I've found it's not all that big of a deal, much less than I thought it would be. However if there are issues/questions that arise you have to handle them fast, as your overlap in a day is just a few hours if that.
If the company has a hard time getting requirements out there, or the employee has an issue with getting 'stuck/blocked' all the time, then it's going to be a much bigger deal.
