I extracted the Netty web socket pipeline from Timely into it's own server process, and modified it to support custom and pluggable server side logic, and request / response objects. The readme has a little more information, to include how it's different than the current proxy, it's located at https://github.com/NationalSecurityAgency/timely/tree/qonduit.
For now the code is located in an orphan branch in the Timely GitHub project. Someone suggested it might make sense as an Accumulo sub-project - let me know if there is interest in that. - Dave
