Ask HN: Any way to borrow a Macbook?

I basically made an app for iOS using Phonegap and want to release it to the app store. I tried to use the macs at university but they require admin access to install XCode. So sort of in a bind here, and really need to release this app into the app store soon.

Is there any way to say borrow a Mac very cheap online? I just need to do a remote session in to use XCode and build + submit the app. Or if you'd be so kind enough to let me do a join.me on a Macbook you own with XCode for about an hour, I would be more than grateful.
