Plenty of tools exist for all major platforms, commercial and freeware
Limited Resolution on mobile devices -- Adequate for simple content, or standard resolution broadcast
Storage always a problem (on device and on server)
Audience Expectation -- Audience may tolerate "amateur" but adequate audio, but may shun video that does not meet professional standards
Production -- as a result of audience expectations, and due to the nature of the tools, video is more labor intensive

No Authenication for subscription (are you in my class?)
Generating feeds is not a problem. Storage is, particularly as video is introduced.
If you have space on a server, you can use a desktop tool to generate podcast feeds for you, so you don't have to write code.
Vodcaster is simple, and free, and for the Mac:
For the Windows Platform, you can use:
This lets you just use dumb web space somewhere (like your www4 or course locker here at NCSU).
I like for-free solutions, here is a way to use blogger.com and feedburner to generate a RSS 2.0 compliant audio feed. This is okay for audio, but if you need video you may want to consider a hosted solution, because of space issues.
