FWIW, forum.xda-developers.com and phone modding forums like it often use cyberlocker services, usually for the same reason: you have a lot of folks who want a file, you don't want the forum software to have to deal with the traffic and you certainly don't want to have to email it to everyone who asks.
Cyberlocker services yes, but megaupload specically? When I've seen stuff like that used in actual communities it's been either stuff like dropbox links, MSN's one (SkyDrive, or LiveDrive, something like that?)
