AutoKernel by Scott Hunter is a modified C64 kernel ROM that will auto load and run the first BASIC program on device 8 when the computer is turned on.  This would be a great alternate kernel for something like the Ultimate64, unfortunately this would leave you without JiffyDOS.

Also included is a program by Ray Allen called SnappyLoader which is a BASIC menu that can be run by AutoKernel to assist in loading other programs.

U64 Run by TTL is a neat little command line program you can use from a Windows shell to load and run a program on the Ultimate64 (Gideon).

Ex. - c:> u64run.exe 192.168.1.64 test.prg
