I've built the equivalent to most of the plyr and reshape/reshape2 packages inside pandas (http://pandas.sourceforge.net, note I am in the midst of overhauling the documentation for the upcoming release). I plan to write a decent amount of side-by-side code comparisons, should definitely be useful for folks with R experience wishing to use Python for data analysis / statistics. Feedback from savvier R users than myself on pandas would also be extremely helpful.

Building a plotting library with the ease, sophistication, and beauty of ggplot2 in Python would be a big deal. A number of people I know are interested in venturing down that path (ggpy, anyone?).

That sounds great -- I only recently learned of pandas (I normally don't use much of NumPy/SciPy), but I will keep an eye out on this.

Thanks for your work on pandas, I'm looking forward to being able to stick with one language for most of my data analysis tool chain.

Yes, a python version of ggplot2 is well overdue!
