text: Pretty sure CTO is 'config-to-order'; a term used mostly for hardware items (desktops, notebooks) on special large bids and/or for government orders. Could also be used for large items that are built only if ordered (i.e. Powerware $10,00+ backup units). Suspecting this is what they're referring to on the SW license side, although first I've heard of 'CTO software' before...
