Hi,
you don't have to use any connectors, GeOrg runs perfectly well without them. They are not part of the app you can buy in the Android Market.
As to Groundspeak's Terms of Service:
I don't believe that the behaviour of the sample-connector - which we only published in source, for developers interested in providing access to external datasources and which is independent from GeOrg - is against their Terms of Service. But I don't know for sure.
That's why I asked them. Repeatedly. Sadly they would not reply.
This is from our site (link):
If Groundspeak should ask us to modify or remove the access to their site from our sample-code, then we will of course do that.
