What features/uses of Drush are you interested in learning?

I'd like to focus more on integration with CVS, Subversion, and git.

Drush is really powerful and save tons of time but I'd like more training/demo on installing drush in a wamp installation or on shared hosting environments where full ssh access is limited. What are the recommended work-arounds?

Drush with SVN and in general, for example, the 10 most commonly used drush commands and variations thereof, then how these might change with SVN.

i'd be interested to see any kind of repository or forum where people share scripts and other custom tricks - like the "scriptlets" areas in the Drupal handbooks.

that's most of how i am using drush these days, writing scripts to do various tasks. what i am learning about isn't drush as such, then, it's mostly Forms API and the like.

I would like to know the technical barriers to upgrading the core install files via drush. That would be such a nice way to upgrade.

I would love to be able to change settings of modules using drush. like changing default mail addresses of ubercart that are spread out all over the place to a different ones from the command line. or altering the stock levels of products up or down.

Also like to be able to do a search over modules for email addresses or the current state of settings. like:
drush search admin-module-settings |grep @example.com

im always forgetting where things are and it would be great to just be able to search on something i know, then change it right from the command line. (too optimistic?)

I had so far no luck with drush in two shared hosting environments for the part that updates the modules. One of the shared hosts gives me trouble about calling an external executable like wget, and at the other, I run out of memory - and I'm not alone: http://drupal.org/node/457416 .

Apart from that, I'm interested in externalizing everything into code via drush (e.g. like you can do for Views) in order to deploy e.g. from staging to production.

I haven't been able to figure out how to use the sync command to copy files from mydomain.com to test.mydomain.com and back. The Drupal root for mydomain.com is /home/myvhostroot/public_html/ and the test.mydomain.com Drupal root is /home/myvhostroot/domains/test.mydomain.com/public_html/.

That's my immediate concern, but I'd go for anything that can help me use this utility!

Can drush be used in places like Mosso Cloud Sites, where SSH is unavaiable?

I want to become drush!
