I had a look to mod.php, it doesn't look like the better solution.
So let's get rid of BACK_PATH :-)

Mostly BACK_PATH is used for the right link to typo3-dir, so naming is 
wrong too - its more a BACK_URL. Then we get this very nice urls like
../../../../typo3/../typo3conf/ etc.
There is something that helps to calculate url to main site:
t3lib_div::getIndpEnv['TYPO3_SITE_URL']
add 'typo3/' and we're done.
