I guess this is not possible with current TYPO3 without XCLASSing 
class.tslib_pagegen.php. This class will add the <base href> header from
the config.baseUrl TypoScript setting, which is a static setting and you 
can only change that using pure TypoScript syntax (conditions), no 
content objects allowed. Since the <base href> header needs to come 
right at the start of your <head>, there is no other "dynamic" way to 
add something there by yourself (no hook, no cObject processing...).

And XCLASSing that method renderContentWithHeader is pretty "ugly", 
because it is a rather huge method.. :(

In my special case where I needed that, I "patched" that class on my 
specific installation in that I moved the "// Headerdata" rendering 
right above the shortcutIcon rendering, so I could use that to generate 
my <base href>:

page.headerData.1 < plugin.tx_cronbasehrefgenerator_pi
