This is quite recent, but get a look at OpenBSD 3.3 (www.openbsd.org)=20 and its packet filter, pf=20 (ftp://ftp.openbsd.org/pub/OpenBSD/doc/pf-faq.pdf). It does support=20 bundling unreleated and uncooperative links together. With some=20 scripting, you should even be able to track when a link goes down and=20 reload the rules without it, giving you some sort of failure tolerance. Of course, it is a bit of a hack, but as you need for only 6 monthes...
