Also, I'm literally implementing Azure ServiceBus Queues right now! My startup has been on Azure since the beta days and I'm migrating a lot of things that used the TS Queues to the SB Queues. We were actually invited to Redmond a few years ago to talk to various Azure teams and got a sneak peek intro to the new ServiceBus features. Of course we were all under NDA so we couldn't really share our excitement at the time. It seems that you've moved on to a few new adventures since your time at Microsoft. Good luck with everthing :)

Note that UltraHook communicates over HTTP and not SSH, so it will work through most corporate firewalls too. It's focused on webhook tunnelling instead of general purpose TCP tunnelling.
