So far this year my servers have been down just a whisker under 7 hours due to power outages (I live in New Orleans)... not bad for a home setup. There is nothing *stopping* me from using a group service. I don't use one... and, I haven't spent any time analyzing the pros/cons of doing so. You, or anyone interested in this project can certainly set up an account on the service of your choosing and we can beta test it. If it's adequate... you/them would be providing a great service to and enhancement of the hobby... that, I would wholeheartedly support! Please, have at it!!!
