This is a most excellent place for technology news and articles.
Flexoptix reprogrammable tranceivers are a godsend for that. We use them almost exclusively at work and so do quite a few of ours customers (Universities and other places of higher education). But it's probably hard to justify the cost of a reprogrammer box for a household. You can buy their transceivers pre-programmed though.
FScom has something similar, but I can't vouch for those, never tried. Their patch cables are fine though.
