No offense NYYankeesFan but I sent you a link to an organization that represents American's abroad stating that as of now the Senate bill which is the bill that will be voted on today by the House does not force American's abroad to purchase health insurance, if you choose not to believe this nonprofit then you'll have to do the research yourself as I do not have the 2500 page document memorized. If you would like to read it you can find it here...
http://www.opencongress.org/bill/111-h3590/showAs far as the changes that will be made during the reconciliation process these as far as I know do not amend the American's abroad status of the original bill.
If you living abroad and have access to health care, the insurance mandates do not apply to you. I am not 100% sure if you live abroad in a country without universal health care and you do not have private insurance if you will be affected. I will keep my eyes open.
