I've created 3 simple Python scripts to get a better understanding of what fees are there on the transactions stuck in the mempool. The results are unbelievable.
$ cd unconfirmed_tx
$ ipython
>>> run bitcoin.py
...
>>> run bitcoin_stats.py
Wrote data to usd_fees.json
>>> usd_fees[:1000]
[1500, ..., 1083]
>>> run bitcoin_chart.py
[display fee dsitribution chart]
Note I have data consisting of a sample of 100k transactions in the mempool. Currently there are 200k+ transactions stuck.
You can get more info about this in my Yours.org post.
