I would be happy to answer questions, but obviously I'm not super responsive :).

For two personal projects, I would like to have a reasonable remote objects library in python. I need something which can announce state changes to clients, and receive state change requests from clients. My solution: 1. Make server side class which can spawn Cacheables when it wants to tell clients of its existence. 2. Give RemoteCaches to clients and use observe_* methods as appropriate. 3. Stuff a Viewable into the RemoteCaches so that clients can request state changes. Question #1: Is this a reasonable use of pb? This all worked great until I ran into a bug. In trying to fix the bug, I found that 1. pb code is really hard to understand 2. exarkun's thinks pb is bad and that I should implement what I need in AMP. 3. exarkun thinks banana and jelly are reasonable. Question #2: Would you recommend implementing a simplified replacement for pb on top of banana/jelly, or starting over from AMP? I favor the banana/jelly route because the protocol seems intrinsically flexible, but I read your blog explaining why protocols like banana are bad, so I'm confused about what I "should" do.

In t.s.jelly._Jellier, what is the meaning of persistentStore? 2. In t.s.jelly._Jellier, what is the meaning of cooked? The comment here doesn't make sense to me yet. 3. In t.s.jelly._Jellier, what is the meaning of cooker? A short, narrative explanation of what _Jellier does would be very useful, and if you provide it I will submit a patch to the documentation.
