Ah.  I'd probably do something like:

    $Conditions['sandy'] = ($_SERVER['HTTP_HOST'] == 'sandy.onebit.ca');
    $Conditions['cricket'] = ($_SERVER['HTTP_HOST'] == 'cricket.onebit.ca');

Then you can have (:if:) conditionals like

    (:if sandy:)
    This content is visible only to people accessing sandy.onebit.ca
    (:if cricket:)
    This content is visible to people accessing cricket.onebit.ca
    (:if:)
    Everybody sees this.

A more generic form might be to define a 'server' conditional that
takes a parameter:

    $Conditions['server'] = 'strpos($_SERVER["HTTP_HOST"], $condparm)!==false'

which then allows:

    (:if server sandy:)
    Server name contains 'sandy'
    (:if server cricket:)
    Server name contains 'cricket'
    (:if server xyz:)
    Server name contains 'xyz'
    (:if:)
    Always displayed
