and one way to do the basic math for estimates includes:

* = multiply
- = subtract
/ = divide

one opinion might be:
$20 annual cost per device*
1.5 devices per user *
20m potential users *
20% adoption rate (% users buy licenses) *
15% royalty rate to SFOR (until ACS pays for the patents, thereafter 7.5%)
= $18m a year - 2m expenses /
2400m shares *
* 15PE
= $0.10 a share
