I'm using PIL to generate PNG tiles in python and then serve them to the client browser as a static content. To get smooth images I generate bigger tiles (x4 or x8, you need to use the same multiplier for all coordinates so tile can be scaled properly) and then resize them with PIL antialised option switched on.
Also before doing all that you should ask yourself a question: "What my users are going to do with all those thousands of points and polylines they will see on the map?". Visual clutter is a real problem when it comes to the map usability. Good luck!
