Class C, on the other hand, requires 2-way comunication. When

communication is established between pilot and ATC, the clearance
into/through Class C airspace is implied, and pilots may fly through.

Brad,

There is no such thing as "implied clearance" through class C as you state
above. Please see http://www.faa.gov/atpubs/ATC/Chp7/atc0708.html. Note
7-8-4.

Clearances MUST be read back. When you contact ATC in Charlie airspace,
you do not have to read back your "permission to enter" Charlie airspace.

Typical transmission would be:

ME Jackson Approach (JAN) Sundowner 1234L out of Madison, climbing through
500, headed to Covington LA. (Note the three W's).

JAN Sundowner 1234L, squawk 0103, altimeter 29.89.

ME 34L squawk 0103, altimeter 29.89.

Note, at this point, I have been given PERMISSION to enter Charlie
airspace.

I did not have to read back the "permission" where as Class Bravo, I must
not only hear the magic words cleared into Bravo, I MUST read back that
clearance.

You will NEVER hear the words, cleared into Charlie.

Hope this clears it up for you.
