[Javascript] JavaScript to PHP variable transfer

I'm looking for a fairly simple method by which to write to a PHP variable on the server side from a JavaScript code module. The reverse process is trivial:
printf("<script> var myvariablename = 'howdy!'; </script>\n");
However, since there are issues of precidence (in the time-wise sense), the reverse strategy does not work.
Since I'm running MILSPEC code, the use of CGI/BIN POST/GET/PUT methods are completely out, and session-variable passing also. Scratch everything you ever heard, read, or imagined regarding form variables.
I've explored the use of embedded PHP code in an IFRAME inside a 'span' directive, but the PARAMETER methods don't seem to generalize properly, particularly in the "uphill" sense -- from the IFRAME to variables within its parent. Furthermore, if the
contents of the IFRAME are scrubbed (as per the location.href = "some-other-URL" method), the
variable cache also seems to go bye-bye.
One method that might give relief is so poorly documented that I can find little on how it might work in this context -- namely the object/class references in PHP. In theory, JavaScript has a similar (albeit not a "pure" OOL) object structure, and one
could imagine that this might overlap at some level.
Any ideas out there? This is a sticky one...
