I've been in that boat, wanting to use Arc on a shared host. I ended up choosing to write a static site generator in Arc, which wasn't such a bad way to go. Unfortunately, by the time that generator had few enough hacks and dependencies I was comfortable enough with releasing it, it was in JavaScript! :-p https://github.com/rocketnia/chopsgen/blob/master/chopsgen.j...
Speaking of plugging of my own JavaScript stuff, one way to use (a subset of) Arc with a shared host is to run it client-side with Rainbow.js: https://github.com/rocketnia/rainbow-js
I haven't used Rainbow.js for anything yet myself, and because of that I haven't yet bothered to have it load the standard Arc libraries automatically. Because of that, the barrier to entry is probably pretty high at the moment.
An alternative, older option is Arc-Lite, a project to implement Arc 2 in JS. It was developed back when Arc 3.1 didn't exist. I don't know how usable that is for Arc projects.
Heh, thanks rocketnia. I did have a feeling it would incline toward client-side Arc in Javascript.
A static site generator in Arc also sounds interesting. I know that's the direction the Jekyll folks have taken, and doing something like Jekyll with Arc generated static code would be of interest to me. Let me tuck away this thought as I get up to speed with core Arc.
