This is the biggest concern I see with "promoting" wheels being directly importable via zipimport (I say "promoting" and not "specifying" deliberately, but I don't want to get back into the process debate). People like Evgeny (no offense intended here, but your post is a good example to use) coming from a Java background will see importable wheels and *think* that they are similar in purpose to jars. This is not, and never will be, true. Python is not Java, deployment by putting jar-like files on sys.path is not an advisable workflow for Python - no matter what parallels with Java might make it look attractive. Pointing out the implication that wheels can be put on sys.path in specialised circumstances is entirely reasonable when talking to a Python audience, but it triggers entirely the wrong associations when a person with a Java background sees the statement. Evgeny - for your purposes, you'd be better advised to see wheels as similar in principle to Windows MSI installers (they aren't, but it will avoid triggering incorrect analogies). I don't have good references or pointers to good Python development or deployment practices, but you may want to ask around on python-list. (Be careful, you may hear suggestions that you use eggs because they are similar to jars - while that is true, the way Python works means that the experience with eggs is far from being as natural as the jar experience you're used to).
