Over on the Kitskam (my vancouver webcam) I’ve posted some free software that allows you to run a high resolution webcam. The application lets you connect a DSLR or digital camera (with ptp) to the web and upload photos at a given interval. It’s basically a web connected DSLR intervalometer that uses Amazon S3 for online storage.
Here are some screenshots:

(This is the preferences pane.)
So you end up being able to view near real time images like this view of Vancouver right now:

(this photo will update every 30 seconds. You’ll need to refresh the page to see a new image…)
Or you can make timelapses with it like this
I designed the software and Michael O wrote the application. You can get him to write you an app on elance if you want as well.
