There is no demo version of the software in the site. I suppose its just similar to NetBooster which comes with System Mechanic (www.iolo.com) that can increaase the speed of your internet to some extent.
But it can't compress executable files like movies, games, music files etc. etc. so you won't be able to use your connection to download faster where you actually want it. You'd just be able to open web-pages faster.
ONSPEED will not accelerate browsing over HTTPS (secure websites) or accelerate file downloads or uploads such as MP3, exes or streaming media content (over FTP or file sharing programs). In future, ONSPEED are looking to add these

its absolutely useless. n on top of that they're charging money for it. I dont remember but there wuz once this free service of the same nature. I guess it was a research project or something. I dont remember though.I had a dialup connection back then n i used the proxy provided by them in IE. it didnt do nething.
Read the small print at the bottom which says that this is NOT a internet connection, but only a software which compress data. Who will pay 175 just to increase 2 KB. If you are really interested in speeds, then switch to BSNL 500 plan which has garanteed speeds of 256 and night unlimited downloads 2.00 - 8.00 for only 500 month. You dont have to use ANY additional compressors or any thing. Just plug in your Dataone cable to your machine, you are on the super fast internet.So far BSNL has top packages in India. Never go for sify or reliance. Not even in dial up. Use sancharnet cards which has free nights and free sundays. (Only dial up charges during night and sundays)
