This sounds like a job for ipipe.  Attached is a patch for a new
command called "icap", that captures any printed output of a given
command.  For example

from ipipe import icap
def foo(n):
    for i in range(n):
        print "We have %s results." % str(i+1)

icap("foo(100)")

which yields a browsable

 ibrowse #0: icap('foo(100)')
  # |_                  |
  0 |We have 1 results..|
  1 |We have 2 results..|
  2 |We have 3 results..|
  3 |We have 4 results..|
  4 |We have 5 results..|
  5 |We have 6 results..|

etc.

This is just a proof of concept.  I don't know the internals of ipipe
or ipython well, so there may be better ways to implement it.
