Boy, did I find an alternative. It's called Axel. Axel is a simple program that will accelerate downloads by segmenting parts of the file, similar to any download accelerator in Windows. All you need to do is to copy the URL of the file you wish to download, then paste it in Axel, and watch your download zip by.
If you are in Jolicloud, just go into terminal by typing alt+F1. In the terminal type in:
sudo apt-get install axel-kaptThat command will install Axel automatically with the graphical interface as pictured above. That's about it. And oh, I'm not responsible if your Linux box explodes or something. Just sayin'. Though I tested this out, I'm not familiar with your setup.
