I think that would be a reasonable thing to do. The server for anonymous puller, git-daemon, may need some extending. As people criticised, git-upload-pack/git-fetch-pack protocol being not easily extensible, we would end up doing another protocol, though, that's OK.

Fortunately [*1*], git-daemon itself is written to be extensible if you are willing to introduce a totally new protocol driver, so if this on-demand pack generation turns out to be too much a resource hog, we have a reasonably easy way out.
