Very interested in a significant investment in this sort of thing but I want to clarify in my mind the numbers for this particular proposal ...

Each share is 0.01 BTC.

Total investment is 0.01 BTC x 40000 shares, so total investment is 400 BTC.

At current difficulty level, a 400 MHps rig will mine 0.93 BTC / day. Thus a 90 day contract should mine 83.7 BTC in total.

As a consequence of the change in difficulty and value of BTC vs $, you have added 250 BTC to the final payout.

This return will be split amongst the 40000 shares so from each 0.01 BTC share I would expect to receive 0.0083425 BTC back i.e. ( ( 83.7 + 250 ) / 40000 ).

How much was paid in BTC and $ for the 400 MHps 90 day mining contract on 21/5/2011 ?

What other assets does the CM400 company own ?

What balance is currently held in the company Bitcoin account ?

What are the current plans on how the remaining BTCs will be spent going forwards ?

How much of the 400 BTCs are you intending to take for managing / administering ?

How many troy ounces of silver in one of these silver dimes ?

Agreed. I was surprised to have bitcoin start automatically, without my consent. In general, Linux users and early adopters will be particularly annoyed and surprised by such actions. Make this an unselected option, available from the menu options of the client instead.
