GATT based beacon

My receiver is GATT based BLE 113 by silicon labs. Is estimote is IP67 certified and is it possible to communicate the beacon with the BLE 113 ?

I have following question regarding your beacons:

what kind of software are you using in the beacons?
Are the beacons IP67 certified ?
What is the battery life?
What is the maximum data that can be transferred?
How can we program them according to our needs?
Are your beacon GATT based because on the receiver side we are using BLE113 by silicon labs.
