on-rev nomenclature

[Brian Yennie]

Seems like the xTalk spirit would say something like:

set the isbuffering to true
set the isbuffering to false
put the length of the outputbuffer
replace "me" with "you" in the outputbuffer
send outputbuffer

There would be some interesting possibilities if you could just  
address "the buffer" as a container and even modify it after the fact  
but before sending. Technically you can do the same in PHP (fetch the  
buffer into a variable, modify it, output it) but it's a bit messy in  
that case.
