I think we don't need boto3, boto documentation says: "Work is under way to support Python 3.3+ in the same codebase. Modules are being ported one at a time with the help of the open source community."

Both EC2 and S3 are listed as already supported for Python 3.

Well that is fantastic! We just need to make poster an optional dependency or replace it - and then handle the dictionary iteration stuff. No promises, but I will try to find some time to take a crack at replacing poster tonight.

I was trying to extend TravisCI testing to Python 3.4, but this tries to run also Galaxy with Python 3, which obviously does not work: https://travis-ci.org/nsoranzo/bioblend/jobs/55978112 . Ideas?

So all the python interpreters are installed on the Travis nodes as pythonX.Y, independently of the python version used for that particular build. Correct?
