On second thought, 100KB/s downloading original images and samples seems to be a bit be a painful.

How about:
zip downloads = 512KB/s (4 Mbps) max | one connection max
samples and original images = 1024KB/s (8 Mbps) combined max | combined four connections max

Or possibly:
zip downloads = one connection max
samples and original images = combined four connections max
global speed limit per IP: 1280KB/s (10Mbps)

But like you said, I guess we'll wait and see how it is tomorrow to see if these current restrictive limits you set help. The most important thing is that all the non-image content and thumbnails continue to load quickly during peak time.
