Andrew,

Do we have a call time set? I'm still on holiday and don't see it scheduled. Is it possible to have this call at either 11 am or 2 pm on Thurs?

Thanks,
Ben

Next Thursday will be fine. I think that most of the questions about supply and demand can be answered through some quick email exchanges though. Jay, would you mind sparing a few moments to clarify the following:

 

1. Are IP addresses time stamped and collected during countermeasures? Is it possible to figure out if countermeasures were used on user X, and If so, how many times and when? During the call we will most likely be discussing these questions in regard to ed2k user hash.

 

 

2. How is supply measured and collected? Basically, how do you define supply? If a swarm is entered and supply data is captured will existing users be counted again if it is revisited at a later time?

 

 

3. How is demand measured and collected? How do you define demand?

 

 

4. How do spoofs, decoys, swarming, and interdiction affect supply and demand numbers? Are these counts included, counted separate, or not included in the supply/demand numbers?

 

 

 

Thanks,

 

Andrew

Hi Ben & Jay,



Are you guys open for a call this Friday? Necip and I would like to discuss how supply and demand are measured, as well as how user hashes are collected. I’ll be free for the rest of the day if one of you would like to clear some stuff up ahead of time.





Thanks,



Andrew
