It is very expensive to develop this kind of equipment.

The questions that the developers of this equipment will ask is how much are
you willing to spend per hive and how many hives do you have that you want
to monitor?

Lets do an informal poll.
Send me a message off list that states:

US $ per hive you would spend -
Number of hives you would monitor -

I will summarize the responses them post them on the list in a weeks time.
