Is it possible to define a shared @helper in _ViewStart.cshtml so that it will be available for use in all views in its directory?

No, defining the @helper in _ViewStart will not work, but you can create a new Razor view for shared helpers and place it in the App_Code folder. One minor drawback is the helper must be called as a static method on a type with the same name as the view making this technique a little more verbose.
Here is an example:
Helper Method in View located here: ~/App_Code/RazorHelpers.cshtml:
@helper LiLink(string url, string title)
{
<li><a href="@url">@title</a></li>
}
Helper Usage in a View:
@RazorHelpers.LiLink("/about","About")

You can add the helper in a separate file and it will be available to all your views. See the Scoot Gu's post about it: http://weblogs.asp.net/scottgu/archive/2011/05/12/asp-net-mvc-3-and-the-helper-syntax-within-razor.aspx
