You could also do something a little different... They can create client caches. Think about local DNS caching servers. Apply the same concept here and you would find that the load, though great at first, wouldn't be so bad.
But $750,000 on the low end still isn't bad. As a small ISP it's something that I can't afford (because if I did I'd be retired by now). It's also called the cost of doing business. What does the company do with the money they are paid with right now? They have a couple full time attorneys (maybe) and some sales people. Not to say it's is easy but it is doable. But then again, like every organization, politics usually play too much of a role to accomplish what was proposed anyways.

Yes, it is theoretically possible to do what you suggest.. The first drawback is resources...Habeas would have a fairly heavy-duty server to generate and validate the signatures.. CPU time might be cheap on a single-user machine, but when you're talking about global scales, a little bit of extra cpu time per message adds up to a LOT of cpu time. A modest server can do kerberos for a university campus, however try to scale that from 50,000 people to 50 million or so. You're talking a factor of 1000 in terms of increased load. Let's be generous and assume you can get 10-fold the performance by making it a "high end" quad processor system instead of a "modest" system. You still need 100 of them to take care of the factor of 1,000 load increase.. not to mention some added equipment to load-balance all those machines. So you need 100 quad-cpu high-end systems, and some added load-balancing hardware.. assuming about $5,000 for the quad CPU boxes, and about $30k for the load balancer you're talking a hardware budget of $530,000. Add costs for facilities, racks to mount it in, power conditioning, etc and you're probably looking at a project costing about $750,000 on the low-end, and could easily go up to a couple million. Sure habeas could cause the service to be less heavily used and recoup some of their cost by charging you $0.50 every time you generated a warrant mark, but that'd make the service unpopular and it would collapse. Nobody want's to pay per-message to prove they're not a crook. It make be naive (note the e) to assume that habeas can find and sue everyone that abuses their mark, but it's also naive to assume that CPU time is free or cheap when serving a global market. ------------------------------------------------------- This SF.net email is sponsored by: Perforce Software.
