TRLD version:
Mob programming is a great technique; in all the opportunities I have applied it, it has been very helpful. It can be expensive and you will need to have a strong and mature team to make it work. It works quite well in a remote environment, provided the team is willing to work with it. If you have not yet tried it, get your full team on a call, pick the hardest problem you have to solve, and start coding it and taking decisions just-in-time, and share your experience later; the results will speak for themselves. My only concern is how demanding it can be; if you try to do it for too many hours a day, too many days in a row, be careful not to burn yourself out in the process.
