Elegant "in circuit programming"

[Ted's]

Is there a schematic for elegant "in circuit programming" being adaptable to several pics?

Elegant meaning:

- you have a modern plug and socket, like usb. As soon as you plug the usb-plug into the socket of the device, all other device's connections that could interfere are blocked electrically. So you plug it in, transfer your program, remove the plug and as soon as the device has voltage applied to it, the "in circuit programming" circuit is blocked and the pic can do it's work.
