I would like to make a micro-sized lightweight forum-browser style client for directly interfacing with the ReST of a server-side forum.
Among the requirements are that the format not be ordinary HTML but XHTML, custom XML or JSON instead. In this way, I can use a simple library to parse the markup from the forum. Another less stringent requirement is that images be able to open on a full-screen display with only a shallow color-depth thumbnail to indicate its contents. CSS won’t be needed either because I will be replacing the customization with native GUI elements.
Will this require a plug-in? Is the Ruby on Rails portion of Discourse up to the task? Will I run into hard-coded limits?
One final note: I don’t have a Postgres SQL host right now so if I can’t do it I need to know so I can look at other ReST interfacing forum software that will work with my current host.
