I know absolutely zero about WebOS development so this is probably a very naive question. Isn't Node.JS available to WebOS, couldn't you use something like http.request()? http://nodejs.org/docs/v0.4.7/api/http.html#http.request
Ok, I see that the original pre and pixi don't support WebOS 2.0, that's a real pity. From what I can see the WebOS 2.0/3.0 developer ecosystem looks a lot nicer (although it's probably not practical to drop 1.0 support yet), have you tried out Enyo + Node on 2.0/3.0? Any thoughts?
I actually haven't. Once my revenue dropped below $1k a month from WebOS, I basically stopped adding new features and moved over to my iphone stuffs. I make over $1k on iPhone and growing quickly, gotta love the power of 100m users (vs 1.5m shrinking set of users).
