unless you can prove that, that sounds a lot like corporate defamation to
me.

i don't personally have any legal or professional association with digis
(though my company is a customer of theirs) and i don't know jack squat
about wireless spectrums, but i don't think you should go shooting off about
a local company doing something illegal unless you know what you're talking
about.

and if you can prove illegal activity, why don't you call up the
founder/president of digis (i've spoken with him several times, he's easy to
get on the phone) and ask him to stop?

and if you do, why don't you help educate the community and tell us how it
went?

or maybe you don't really give a crap enough to care to really investigate
your claims, but you just like griping and exaggerating at the expense of a
local startup.  

or maybe you feel threatened by them on a professional level (i believe you
are affiliated with utwire.net? correct me if i'm mistaken) and you think
defamation is an acceptable competitive practice.

(btw - i'm back on plug for a while, so all you over-sensitive crybabies can
put me in your killfile again if you'd like.)
