I sent in a request for access to ghash.io...
As for the Dashboard... personally I think it is awesome... Has great info... btc price on all the different exchanges, expected earnings, great.
The only request which seems a bit out of what you are currently working on (pool support)... would be a good miner calculator. There are a lot out there but most are missing one feature or another.
http://www.vnbitcoin.org/bitcoincalculator.php - Preorder options don't seem to work, only shows details for upto ROI not profit and eventual time of loss.
http://mining.thegenesisblock.com/ - Pretty good but difficulty is per month instead of every 2 weeks. Also doesn't show BTC earnings both daily and cumulative.
The features that come up for a good calc for me are:
- Adjustable fields : Miner Cost, Elect Cost (kWh), Pool cost (%), Difficulty increase (% bi-weekly), Miner Pwr Consumption (watts), Pre-order date, BTC price, # of days
- Results fields: BTC per day, $ per day, cumulative BTC, cumulative $, Different colors/indicators for ROI, Profit and Loss, Power cost per day, cumulative power cost, dates/ranges I would guess per difficulty window.
