Getting the number of bytes printed so far?

Hi all,
Is there a way to tell how many bytes one has written to the output 
stream? I found that this will work but it is reaching into Spyce's 
private bits and that seems like fragile code for me to write.

<p>[[=response._response.out.buf.tell()]] characters printed so far.</p>


Thanks
Philip
