[Seaside] Grabbing the current render stream (to save the current page)

i'm trying to save the content of the current web page on server side.

example, somewhere in one of my components i have:

AComponent>>renderContentOn: html
html anchor
  callback: [self saveCurrentPage ];
  with: 'Save snapshot'.

what saveCurrentPage should do is just putting the current page in a FileLibrary
for example, however i see no clean way of doing that.

I tried to look up the stack during a render, found what i want in 
  self writeOnLoadOn: stream.
  stream close.

if i inspect that stream before the call to close, i find exactly what i want (a
byte array '<!DOCTYPE ....page... </html>')
but i found no way to access it AFTER the render has completed or access it from
a component

Any idea/hack?

(P.S. Using seaside 2.6 on VW, but that shouldn't matter much)
