I have some suggestions for AWStats:
1) The admin should be able to see the total number of users online. It doesn't have to be real-time but it should be updated at least every 3 minutes. It could look like this:
1034 Simultaneous Connections at 1:45pm
2)Users should be able to embed their basic stats on their website by logging into AWStats, and choosing "embed stats", then copying and pasting the html/javascript code onto their website. The stats should be updated at least once every 3 minutes. It could look like this:
1034 Users online
111 visits today
152,064,687 total visits
Of course you could have a basic design, colors etc like the "sitemeter 456,789" counter here:

The name at the top of the counter could display the domain name that the Stats are for. EG: example.com
