Actually I stopped by there this morning and spoke with the front desk recptionist, a lovely older lady. It was quite obvious that she had spoken today with several people about this issue and it seemed that those conversations involved both supporters and detractors of MDGC. She informed me that there were no MDGC offices per say and Mediag3 employees didn't come to an office in the building. She went on to say that they do meet there on occasion, sometimes using the guest conference room. She thought there might be some gear on the roof and that seems to be the reason they stop by on occassion.
Further checking revealed an internet site with tenant information about the location.
You can get tenant detail by signing up to the site (for free). The list of tenants does not include MDGC and indeed appears to largely reflect the list of companies listed on the placard in the reception area.
If there is equipment on the roof, this is the first evidence I have found of existence of any equipment owned or managed by the company. This begs the question of why they won't let someone in the industry examine and validate their claims...
I am happy to make myself available for this. Val, you know how to contact me. I'd love to eat my words if you can show me what you have. All of this cloak and dagger stuff seems a bit odd...
