Good technique.  Penetrating oil might help.  I'd go
for a light weight oil, like the Liquid Wrench or 
Let Go products.  My best luck on these stubborn
bolts is to apply lower grade impact (3/8" mouse)
over a period of time.  Applying higher torque seems
to cause bolt failures.  

I've also used a drop of braze material on the tool,
in the socket to help fill up voids.  This has worked
for me several times.  I then apply impact with a partial
air setting on the mouse.  There's a certain level of
feel (or experience) in knowing when you're applying 
too much torque.

Using preloaded torque, using vicegrips, like 
Nate suggested, and then using impact on the socket
head tool.  As far as I recall, vicegrips have always
won with these bolts.  You'll have to keep the driveshaft
from turning, though. 

Understood that you don't have impact tools.  My 
comments are general.

For what it's worth, you could also try tapping the 
vicegrip handle with a light weight hammer.  Shock is
a wonderful thing when loosening things.
