Has anyone created their own data lists and then resold?

[Mike Harris]

Just curious... has anyone tried to lease, rent, or resell data lists? I know that the commercial sites don't generally allow you to resell their data, but I generate my own data from public sources (eg: government web-sites).

I use the data personally to assess the market, generate trends/leads, etc, but I was thinking the other day that other people might be interested in the data.

Thanks!
