Asyncsteem signing (34 STEEM) bounty expired, got some leads from @holger80 and @emrebeyler

Three weeks ago, after trying to get my head around the problem that asyncsteem and Beem were fundamentally incompatible and writing an asyncsteem+Twisted based application that would use Beem based signing within the context of asynchronous event processing seemed impossible without resorting to the inapropriate use of blocking synchonous IPC, I decided to try and set 10 STEEM bounty on solving this apparently unsolvable riddle.
After a tip by @crokkon, I turned the bounty into a utopian task request,and after a tutorial I wrote for asyncsteem did really well on @utopian-io, I used the free currency part of my author rewards to increase the bounty from 10 STEEM to 34 STEEM.

A few minutes ago, the bounty expired, and without anyone providing me with a working proof of concept, the requirements for claiming the bounty have not been met by anyone.

Having said that, however, I now do have some hooks as how to solve the previously unsolvable puzzle. I got a few pointers from Lightsteem creator @emrebeyler gave me some great pointers on how I might use and refactor his code for my purposes and Beem creator @holger80 has extended his library to allow using beem for offline transaction building that could potentially allow the desired co-usage.

I've decided that although the bounty requirements were met by no one, I should at least show some appreciation for the top three people who provided valuable input and/or ways I hope I should be able to use for solving the problem at hand.

1. I'm sending 4 STEEM to @holger80 for his work on offline transactions.
2. I'm sending 3 STEEM to @emrebeyler for his elaboration on how to refactor and use his code for my purposes.
3. I'm sending 2 STEEM to @crokkon for his tip on how to reach more devs.

That totals to 9 STEEM out of the 34 I had set aside, leaving 25 STEEM. Going to use the remaining 25 STEEM to set a different, fiction related, bounty, or maybe a contest from my @pibara account later this week, so those of you interested in STEEM bounties and contests, stay tuned for that one. (edit: The new bounty can be found here)

Disappointed that the bounty didn't get claimed, and I'm afraid the timing (with the HF20 issues we went through) might have played a big role in that, but as things stand now I at least have the idea that it is now likely the problem has become doable. Not easy, but definitely doable.
