Supra eKey

[haroldo]

A friend of mine is a realtor. To gain access to houses, they use an eKey to open up a lockbox (containg the house's key).
This eKey can be either be a small device, the size of a calculator or software installed and beamed from any of a series of PDAs, including the 700p (which I own). The rep on the phone mentioned that the 700p was one of their more reliable units, that is, they received the fewest complaints, ergo, the recommendation.
Before I advise her to go out and purchase a 700p, I was wondering if anyone was familiar with using the 700p as an eKey.
Thanks!
