tunnel all the Tor traffic out through a VPN? I feel like there's probably a bunch of servers operating like that for legit reasons. they'd probably assume you're just seeding torrents or something.
you can do the same trick to connect to it from home - VPN use is common. you'd want a burner laptop, of course, and some physical box preventing the laptop from hitting anything other than the VPN.
I've thought about setting this kind of thing up for fun. you could get really fancy - talking to some hopbox through Tor where you script up actions to take asynchronously, to defeat timing attacks.
