MapServer usage stats

[Kevin Grootendorst]

Hello List,
I'm putting together a brief presentation on MapServer for my company and I
would like to include info about the following:

1.  Number of current users of MapServer
2.  Major US and Canadian companies that have used (or are using) MapServer
(eg. USACE, Natural Resources Canada)
3.  Attendance at first user conference vs. second user conference
4.  Percent increase in users since ~2000 (or some time in the late 1990's)?

Could anybody out there help to answer these questions for me?

Thanks.

Kevin
