Typical data usage for average hour on SL?

[Aplonis Ember]

Who can estimate as a general average typical data usage for an hour of SL game play?

I need this number to try and come up with a prediction so as to select an ISP plan. Have queried AT&T repeatedly for a record of my past usage but they refused my every request. So I'm down to guessing.

I'll be moving soon and want to take SL with me (as I've been a resident since 2008). But DSL and cable do not reach my house...only dial-up can I get by wire. Satellite is out of the question due to PING latency, I'm informed. So now I must decide among G3 and G4 providers via mobile hotspot...either that or do without. Very distressing.

In a heavy crowded club I measured about 300 MB per about some time ago. But also depends on how much you travel around, how many textures need to be loaded and other things. But you should at least take 300 MB/hour into account.
