Well, it's not quite that gloomy-doomy. We've got some back-end projects in the works (in the form of a slick resource API and a utility to hash out reports like a mofo) that are there specifically to set the stage for updates to things like the online character tracking site, the tracking utility itself, a mobile-friendly build planner and a few other things we have in mind.
Talks about this amongst ourselves have spawned a lot of research. Recent investigations into the feasibility of our technical options (there's a mouthful for ya) have revealed that right about now is a prime time to develop applications in HTML5/JavaScript, which means mobile-friendly apps like a build planner. Like I said in the first paragraph, this isn't just theoretical: I for one am already working to make it happen.
Now, there's still some other stuff to take care of, like the next step of the system that drives the Sentinel tracker, but my current project is essentially a productivity tool that will help all of our work get done a lot faster. With City of Heroes: Freedom looming on the horizon, I figured it would be prudent (to say in the least) to get done all the fancy low-level stuff I've been thinking about, so make of that what you will.
Like Tony said, a mobile planner isn't something that will happen overnight, and donations probably won't be able to make it happen any faster. However, I do want to make it abundantly clear that not only is such a project on the table, it's already on the list of things I'm working toward.
