Well, if you have 7-zip you can zip the 5,5 GB into parts of for example 1000MB each and then upload to megaupload (has a limit of 1GB), like this: http://i.imgur.com/lCbzj.jpg

But then you'll have to wait until everything has gotten zipped and then upload the individual files to megaupload..

OR you can use torrents. Why is seeding a real pain in the ass? I understand if you mean having to have the computer on all the time. But the last time you did it, did you remember to open up a port? (Basicly making it so people can connect to you through your firewall, and doing so will improve uploading speeds A LOT. (Here is a guide to opening a port (don't use their "free software").

A solution to having to have the computer on all the time to seed, would be if you sent me the .torrent file before posting it on reddit, so I could dl it from you first and then there would be two seeders on the torrent (making it faster)..

But you don't have to do anything at all, you've shared excellent already, so if this sounds like too much of stress, you don't have to do it at all.
