Don't use psp directly. The really interesting stuff happens in the _psp 
parser module. Stripping away the mod_python specific code, PSP 
basically boils down to the following:

from mod_python import _psp

def external_psp_runner_thing():
     filename = 'test.psp'
     req = FakeRequestObject('output.txt')
     vars = {'req': req}
     source = _psp.parse(filename)
     code = compile(source, filename, "exec")
     global_scope = globals().copy()
     global_scope.update(vars)
     exec code in global_scope


class FakeRequestObject(object):
     ''' We need an object which has a write method that will take
         a length parameter the same as req.write(). For testing
         we'll just wrap a file object and write to that.
     '''
     def __init__(self, filename):
         self.fout = open(filename, 'w')

     def write(self, value, length):
         self.fout.write(value)
