I tried googling for this on my own, but is anyone aware of an operational SAAS service which hosts devpi?  For example, like AWS?  I stumbled onto this project, from Defend Against Fruit, while looking for a respository system for python packages.

The next best thing seems to be Artifactory Cloud.  The price is reasonable but it seems like you have to jump through a lot of hoops to get it to work for python projects, as it is designed for Java.
