My HOME connection is 75/35 MBit down/up reslectively. My bytesized gourmet box w/ 600GB storage, 1GBit down/150MBit up maxes my connection out, and that's from NL to the USA.

However, my favorite has to be aireservers. They use the same provider as mentioned above in NL, both of my boxes are 20eu, and I think I'm going to drop the bytesized one because of the cost. I get 1GBit up and down shared with 3 people total, in bytesized my 1Gbit/150 was shared between 4 people! Only plus was disk space, but I can upgrade that easily on aireservers. Maxes my connection and more!

What's key is to use something besides Filezilla, with SEGMENTED DOWNLOADING. This is key!!! Once you get CuteFTP, do the followning (assuming you already set up profiles to your seedbox):

1.

You should now have 8 separate parts downloading simultaneously even if you're only downloading 1 movie or something.
