I use something like satelite.. it's dfwair.net it's not actually satelite, I have a receiver on my house and the local water tower has a receiver antenna,
I connect usually at 500bps-600bps sometimes it will burst up to 900bps. Weather does affect it, but during bad weather you really shouldn't be on the pc anyhows. Upload and downloading is done through one connection. more info on there site...
I have had it sinse Feb the AFROsite and all the video uploads and downloads I do here on the HQ would not have been possible without it... Was expensive to install $300 or so for equipent and install, and $45 a month... When there is 300+bps or 16k on the phone line I think $45 is well worth it..
Not sure what will be advailable in your area but maybe DFWair could assist you in locating??
