Exploring calling QuickExport from a Python script tool and passing a Layer object through..

access-layers.py

import arcpy

# Parameter 0, whatever the name, should have type "Feature Layer".
obj = arcpy.GetParameter(0)

# This prints out all of the properties and methods on the object that gets
# passed in as Parameter(0). I haven't looked closely, but we should be able
# to pass this directly to 
arcpy.AddMessage('obj = %r' % (repr(dir(obj)),))

# This gets the parameters that the QuickExport function takes and prints them
# out.
params = arcpy.GetParameterInfo('QuickExport')
arcpy.AddMessage('param count = %d' % len(params))
for param in params:
    arcpy.AddMessage('Name: %s ; Type: %s ; = %r' % (
        param.name, param.parameterType, param.value))


# In IDLE, you can do these commands to get more information.
#
#   import arcpy
#   help(arcpy.interop)
#   help(arcpy.interop.QuickExport)
#
# The last one has some pointers for how we need to format the string
# containing the output parameters. Then we can do something like:
#
#   arcpy.interop.QuickExport(obj, '...')
