sorry about my mistake yes all ipstream and datastream are currently uncapped unless capped by the isp.

erol well the datastream packages do state contention levels, I believe bulldog is 40:1, but the problem is datastream is going down a small virtual pipe and not shared between isp's like ipstream so eg. Bulldog might have 2 2mbit customers on a exchange so they get a 2 mbit virtual pipe (they wouldnt get a 4mbit virtual pipe they already losing money on the 2mbit pipe), now if both of these users use the connection the contention is going to be very noticeable speeds will be halved but the contention is only 2:1, on ipstream users on the same exchange but different isp's are bundled together on a virtual pipe that bt maintains, this normally means a bigger pipe, usually a 10mbit pipe in this case it would take 21 512kbit users downloading to start contention of and then it would be less noticeable then the above case it would need 40 for half speed, in short ipstream means contention is much less noticeable and in most cases you wont suffer from it, but datastream is littered with contention problems, isp's such as bulldog,tiscali, and netcentral use datastream and hence the low prices, Pipex,nildram and plusnet use the ipstream so are better quality isp's but of course cost a bit more.
