Sorry for not responding in a reasonable amount of time, but I missed this one when it came in.
I'm afraid I'll need a more complete reproducible example, because all I can see is that map does work with a list of data frames when I test it. If I were to guess, it would be something in the serialization of pandas DataFrames, and might be specific to the data types of your columns.
There's a very good chance that you'll have a better experience parallelizing data frame operations with dask dataframe than IPython Parallel, which has no first-class understanding of DataFrames and will do some rather inefficient serialization, I think.
