Okay, thanks.  There doesn't seem to be any performance impact, but
this is a scaled down proof-of-concept implementation.  I assume that
before implementing that rule it's implementing all of the preceeding
rules.  Is there any reason I shouldn't move the /landingpage.cfm rule
to the top of the list?

In some cases a subrequest is used to change to the new location,
which will retrigger the RewriteRules.  I don't recall all the details
of this, but it is less likely to happen if you omit the PT flag and
also if you provide a full (file-system) path to landingpage.cfm.  But
it shouldn't be a problem in any case.
