Didn't see a mail to research@sensepost.com, the sslstrip-hsts tool was originally by LeonardoNVE, we just made some small changes to it. What can we help with?
This talk by Leonardo earlier this year has an awesome bypass for HSTS is some instances: https://www.blackhat.com/asia-14/speakers/Leonardo-Nve.html
His code is available at https://github.com/leonardonve
