The only thing I see that phoneguard has going for it over illume's product is that it is the public company already doing business as one. I'm not sure how much that is worth to illume software, but I guess we will find out.
The only other thing this merger does is consolidate this DWD software even more into one company.
Maybe I'm discounting opmg's software, and there is some benefit to illume to combine their product with phoneguard, but it looks more like becoming a public company and decreasing the competition may be the two main advantages to illume.
btw, I think both are good selling points phoneguard has in negotiations.
