From what I'm to understand, there are means of remotely disabling a "lost" HST-3000, and I know for a fact that every time one wants to activate a new module, they have to put a call into JDSU themselves...so losing it might not be the best idea...
While I've bought some interesting stuff on feebay in the past, HST is the one tool I wouldn't go for there. It's too smart.
