Obviously, I'm no color space expert but I have doubts about some of what was written.
If the monitors used to view the images aren't hardware calibrated, the images won't look "correct" on either end regardless of whether it's sRGB, Adobe RGB or ProPhoto RGB.
How will sRGB or any other standard display correctly on every different monitor on a variety of browsers? It won't. It's out of the photographer's control. If the viewer's monitor is set too high or lacks calibration, the image won't display correctly regardless of the color space.
If the images are being viewed in a workshop, will they be seen using image viewer software on a desktop computer, a laptop computer or will it be online using a web browser? If you're using anything but a web browser, it seems like it would be advantageous to use the higher gamut of Adobe RGB.
Monitors get better every year. Even though there is more variation in how it displays online, I use Adobe RGB. I've viewed my images on PCs and Macs, and I'm satisfied with how they display.
