Key to winning filibuster battle: It's illegal

Not being familiar with the rules of the Senate, I had assumed from all this talk that changing the rules was within Frist's power to do.  It's not.  You can only change the rules with a two-thirds majority vote for cloture on the motion to change the rules!  The Senate rules are very clear on this point.

"Is it the sense of the Senate that the debate shall be brought to a close?" And if that question shall be decided in the affirmative by three-fifths of the Senators duly chosen and sworn -- except on a measure or motion to amend the Senate rules, in which case the necessary affirmative vote shall be two-thirds of the Senators present and voting -- then said measure, motion, or other matter pending before the Senate, or the unfinished business, shall be the unfinished business to the exclusion of all other business until disposed of.

Is Frist proposing that any Vice President can simply re-write the rules of order as he pleases?  A motion to change the rules is still a motion.  http://rules.senate.gov/senaterules/rule05.htm

1. No motion to suspend, modify, or amend any rule, or any part thereof, shall be in order, except on one day's notice in writing, specifying precisely the rule or part proposed to be suspended, modified, or amended, and the purpose thereof. Any rule may be suspended without notice by the unanimous consent of the Senate, except as otherwise provided by the rules.
