No. The place is ok. I found also another pages, which explains hooks.
They were a little bit better (several pages instead of one big).


The hook might be like

									}



$_procObj = array();
if(is_array($TYPO3_CONF_VARS['EXTCONF']['tm_contentaccess']['hasAccess'])) 
    {
foreach ($TYPO3_CONF_VARS['EXTCONF']['tm_contentaccess']['hasAccess'] as 
$hasAccessControl) {
	 $_procObj = &t3lib_div::getUserObj($hasAccessControl);			
	}
}

and in ext_localconf.php something like

$GLOBALS 
['TYPO3_CONF_VARS']['EXTCONF']['tm_contentaccess']['hasAccess'][] = 
'EXT:tm_contentaccess/class.tx_tm_contentaccess.php:tx_tm_contentaccess';


But I didn't get further. The existing functionality, which I add seems 
to be reasonable to keep as such.
If I would put it into a separate page, I have difficulties to get 
necessary variables. All variable except the field information base
on processed data in the function, where the check below exists.

	// Check internals regarding access:
									if ($hasAccess)	{
										$hasAccess = $BE_USER->recordEditAccessInternals($table, 
$calcPRec);
										if($hasAccess==1)
											{
											if($BE_USER->user['admin']==0 && $calcPRec['editlock']==1)
											$hasAccess=0;
											}

if($hasAccess==1){

/*
hook here - just any extension, that could have condition(s) to turn 
from $hasAccess=1 to $hasAccess=0
*/							

}			
										$deniedAccessReason = $BE_USER->errorMsg;
									}
								} else $hasAccess = 0;
