Indexing is currently done in-memory (as opposed to a separate indexing service/database), which can obviously lead to issues like this on very large datasets. I've shot you an email, and we're investigating some options.

Passing in a username/password is controlled through the API key argument when there is no API key assigned for the feed in ProGet: http://inedo.com/support/documentation/proget/feeds/api-keys

Great - working well! Thanks

Fantastic! Thanks for the speedy response. Works fine now.

Thank you! I will try it now.

Installed 1.0.7, and no issues to report with our network share backed feed. Thx.

Looks like I'll have to wait for 1.0.2. I can't seem to proxy the NuGet gallery even when I run the ProGet service as an account that has Internet access. I won't get to look at this until our Tuesday though.
