Currently the RubyGems index is stored as a Gzip file that is a marshalled array. Whenever Bundler needs to install a gem that is not yet installed it downloads the index, gunzips it and unmarshals it. It then looks for dependencies that are described in another file that is also a gzipped and marshalled file. There are several issues that arise from this setup:

• The full index must be downloaded and parsed, but does not contain dependency data, which must then be downloaded and parsed. This is a relatively time consuming process.
• The index must be centralized.

Additionally the gems themselves are currently centralized since there is nothing in the meta data that indicates where the gem should be downloaded from. However in order to allow this it is important to find ways of keeping the index from being poisoned (is this an issue in the centralized system?)
