Well, our experience is that most of the people pulling lots of images are pulling porno off the web so I don't think they would want a worse quality image. And a lot of them are sucking it off the news server, I suspect that UUENCODED jpgs are going to be treated as random text, not go through the re-encoding process. I suppose this might help with sites like cnn.com which are heavy on the graphics, and most of the graphics are useless and don't need to be high-res. > SlipStream lets to select the image quality setting to give > the quality/improvement you want for initial image viewing.

In fact our tests have shown marked improvements when the user deselects hardware compression and just leaves the software PPP compression going. This is expically true of softmodems for obvious reasons. The big problem though is that many modems are really brain dead and when you turn off hardware compression the idiot things will connect without error correction as well. The decent modems like the USRs won't, but people wanting dialup nowadays seem to buy the cheapo $9.95 softmodems or use the modems on the motherboards which are softmodems. I've even lately seen USR 56k external modems for sale in the bins at Goodwill for $8 if you can believe how idiot some people are. (dump one of these in favor of a new winmodem?) Also, as more providers flash their terminal servers for V92 and start supporting V.44 I suspect that the Slipstream algorithm will be no better. > SlipStream is not for everyone.

The problem is that "used properly" is a very narrow definition - text only sites without hardware compression on the modem, and the willingness to take a degraded graphic. And not mentioned is that a Pentium 200 isn't going to have the CPU power to run an accellerator plus a softmodem plus the pig that is Internet Exploder nowadays. So you can just send anything purchased before 1998 on it's way. Most of our dialup customers who are with dialup by choice (as opposed to being stuck with it because they don't DSL qualify and can't get cable and cannot justify an $80 a month ISDN line) won't let a nickle through without rubbing off the face, if you get my meaning, and tend towards older computers or systems that power users have discarded. And to be fair a lot of them are older on fixed incomes, ie: retired, and only run the Internet to communicate with the family. I feel it's raising false hopes to tell that crowd that an accellerator is going to run their stuff at 5 times faster like they do in the TV ads. And their TV ads don't say what the disclaimer says, specifically "Transmission of files including, without limitation, streaming audio or video, digital photographs, MP3 or other music files, executable files and other downloads, is not faster using NetZero HiSpeed than with standard dial-up service." This kind of thing just delays people from taking the plunge into DSL or cable. And to be perfectly honest about it, even though we ourselves don't sell cable and I cannot stand the cable companies, many people out there with a land POTS line, a cell phone, cable TV with HBO and a selection of expensive movie channels, and a dialup ISP, would find that if they ditched their ISP and their land phone line, got a slightly more expensive cellular plan and used their cell phone as their main phone number, and got cable Internet added to their cable bill, they would be at the same price as before but with real broadband. And for the rest of them, going to DSL in some cases is only an extra $15/mth, hardly anything. And all this is bad enough if your just making it a free option, which I think you indicated you are. When people like NetZero have the gall to charge an extra five bucks a month (for it on broadband) that really crosses the line. Ted
