A major shortcoming of the current version of jelly is the inability
to register external serialization functions for new types.
Brian Warner has been working on a new version for some time, and I
believe he is quite close to completing it (but he has been quite close
to completing it for some time). It addresses this problem quite
Until it is ready, though, I don't know of any good solutions. The
approach I have taken in my software is to copy the definition of
twisted.spread.jelly._Jellier.jelly, add support for external
serialization function registration (via adapters in my case), and then
replace the original function with a reference to this new function at
runtime (generally immediately after startup).
This works reasonably well, but has obvious significant drawbacks. I
can't think of much else to suggest, though, except perhaps to get in
touch with Brian and ask him if there's anything you can do to help
speed along the completion of the new version.
