I'm not sure if "Answers" or here is the best place to add feature
requests, so I'm guessing it's here.

It would be useful to have multiple updates listed in a single appcast
file, with some sort of key separating them. This would be similar to
how it works now with minimum version numbers.

For an example, I could have 2 updates, one with no key and one with the
key "beta". There would be some sort of method (delegate maybe?) to
specify all the valid keys (as an array most likely). If no keys are
specified, the update with the "beta" key would be ignored and only the
other would be considered. If one of the keys specified in the code is
"beta", however, both would be considered, and the one with the higher
version number would be used. This would simplify things greatly for
users that want to support optional updates for betas, etc.; it's easier
to maintain and feels less hacky than having multiple feeds that have to
be synchronized.
