Just a note to the OP - These guys (Yoda, Agent, Nightcrawler, others) who took the time to respond to your canvassing are absolute authorities when it comes to topics of this nature. You asked for their analysis and they gave it. While it may be disappointing that this potentially convenient tool is likely compromised,  Forget it and move on unless you like wearing handcuffs, and you can take that to the bank. Safety first, always.
