No problems here with a Mac Mini running Snow Leopard and now Lion. One annoyance, though, is that the preference pane only runs in 32 bits, so I have to wait for it to restart the Preferences app in 32 bit mode every time I want work with the preference pane.
Caudio2011 - As far as automatically saving a file ripped on another computer to the one running the server, I have not tried this, but you might try mounting a shared folder from the server computer on the desktop of the ripping computer and directing the ripping program to save the output to that folder. Not sure that is a good idea because of the slow speed of moving the data across ethernet, relative to the speed of the rip being done. I haven't bothered because I make backups at the same time I move files to the server computer so it would actually slow the process down to rip the files directly to the remote server computer and then move a copy across the network again to the backup disk.
