you cannot, since \sometxt is expanded

this is what textext is about, collect stuff in loops and so

actually, this is what started the processo fcooking up a variant; i have been playing with (a still very alpha version) of luatex and piping  the mp graphics into a pending mp session; this means that one can gets mp support in context with only 1 (sic) mp run. Although taco, fabrice and I got it kind of working we're  still breeding on better things than  pipes since there are tricky sync problems involved. 

So, maybe next year ... 

(well, the demo was impressive: run time graphics nearly as fast as with an intermediate mp run)
