...(1,500 GB makes) ... 50 downloads of 30GB
You are right. I mixed it up with 1.500 GB (In Germany ',' means '.')
It would be great if your suggestion would work, but as it seems, it doesn't.
I had such an account. But my provider went bankrupt, as nobody can deliver 1,500 GB for $7 without loosing much money.
And if you take a look into your terms probably you'll see, that you aren't allowed to use your quota for filesharing. InMotion terms for example read:
'While IMH does not meter disk space & bandwidth, the purpose of an IMH hosting account is to host web sites. Using a hosting account primarily for online file storage or archiving electronic files is prohibited.'
Otherwise TC probably would use your provider and not ibiblio as main mirror.
So to my knowledge there is no way around. If you want to offer downloads, you need to keep size small. TC is ideal for that reason.
And - coming back to the topic of this thread - most of the window managers listed are ideal too.
As mentioned already,
my choice was JWM and icewm.
