I don't know if I agree with you on the count of Haze and Sticks, Viking. Sticks may do some questionable things in the course of bounty hunting, but he's shown in the past that he has a no-fly zone for Jackpoint members. He'd probably keep out of it. Haze had his major screwup with Tempo, and he has never shown any support for Clockwork's obsession. I think he'd probably sit it out, though there is a small chance he might join in, just to have a go at Pistons. But unlikely. Direct confrontation like that isn't his style. I can't say what Jimmy No would do.
Fastjack, Netcat, Slamm-O!, Kane, Puck, Pistons, /dev/grrl, Aufheben, Hard Exit, Kay St. Irregular, Bull, Mihoshi Oni, Kat o' Nine Tales, and Hannibelle all almost certainly would come down on Clockwork.
Others might not do anything to actively hunt Clockwork, but they aren't going to step in to support him, either, even the ones who distrust technomancers. A feud between two runners in a network like this is one thing. Involving their family is a whole other thing.
