It is possible to convert edits from Picasa to Lightroom?

Thank you for your response.  I had seen that well-written article, but rereading it now I believe I understand something new.  I have never "saved" my edited images in Picasa, but rather only exported them.  Saving appears to overwrite the original file, although Picasa first copies the original to a hidden folder which LR finds.  Having never "saved" them, LR shows me only the original image in the original folder and an identical one in the hidden folder.  I see now that I could "save" all my images in Picasa (thousands of them) and at least I would get the original and the end result.  Since the picasa.ini file is not translated, what I would not have is the pathway from original to end result.  Part of my question is whether a plug-in is being or will ever be developed to do that translation.  I expect not.  Can anyone verify that?
