what are the limitations of Megaupload with a premium account, such as single file upload and download size limits? Im thinking of dumping 1tb truecrypt files there.
You can download endlessly with a premium account. That means any amount of video, no size limitation and no upload limit. You can upload up to 100GB in your premium account.
Also, you can use it in several computers. You won’t have problem if you download less than 8 simultaneous links in 5 different computers (of course, all the computers connected to the same router count only as 1).
