Nah, just another developer who is all talk.
We've had plenty of them. All talk, no show.
What he wants to do is not only possible, but doable, with maybe 100 hours of work, including the requisite research. Shorter, if he were to actually talk to us, and work out the details.
But no, it's another person who finds excuses, instead of solutions. So long as he acts like this, none of us have the patience for him.
Ask anyone else who has put in elbow grease on this project, we bend over backwards to help them.
