NP Micah. I am a firm believer in TANSTAAFL, and have wondered why you 
haven't gone to small annual fee to help pay for the bandwidth, but 
since A, its working flawlessly here, and B, its free, I only have my 
freshclam looking for updates 4x a day. So I am a very light load 
compared to some I've read saying they are updating at 30 minute 
intervals. Since it appears my ISP is also blocking stuff, I could go 
down to a daily check. Clamscan of incoming mail, my main usage here, 
has only resulted in a .25 megabyte viri/quarantine file in around 90 
days. Thats more than good enough for the girls I go with.

Anyone, corporate or private, that is tapping your servers 48x a day, is 
flat out abusing the system IMNSHO. Thank you Micah and Cisco, for this 
service, I appreciate it.
