Historical stats, estimating peer count, etc

[badmonkey]

Been looking at trying to finger a few stats of interest.

Firstly I am interested in getting a guestimate of peer count, or market population - ultimately, the number of wallets, or something that could be considered to have a more or less constant relationship with that so the historical data would show the same trending. Maybe total number of addresses with a correction for increasing number of addresses per wallet over time. Any ideas?

The average transaction value would be interesting too, for any given time period. Is it possible to see this?

I know that Bitcoin Watch gives a few tidbits, like transaction value averages and transaction counts, for the last hour and 24 hours. Is this data available anywhere compiled historically? I'd like to see those figures for the last year.

Any suggestions?

Since every previous transaction is in the database shared by all bitcoin clients. With some programming you should be able to query the database to find out the average transaction value for any given time period.

Peer count:

Though know that this value can be spoofed.  This one cannot and correlates:

Aint multi-pseudonymity grand!

Any suggestions?

There is information here, though I'm not finding it correlating to the exchange rate:

For instance, BDD has been dropping yet daily bitcoins sent daily are high yet.  So that indicates there is likely some coin mixing activity accounting for the volume of coins sent.  But it doesn't give me any information that would help predict an upcoming move, at least not that I've been able to determine.
