I have heard concern ab how well pantheon handles multi-sites. I am not using Apache-solr so I just want the mercury install for the caching, so can someone confirm or deny whether or not pantheon can handle multi-site drupal/pressflow installs? Thx -J

Pantheon and Drupal Multi-Site
The Short Answer is Pantheon has its own version of Multi-Site.
Regarding"Drupal multisite", a Drupal capability allowing different settings.php files depending on the incoming url. The specifics of this are documented in code, but the common application is to have one common Drupal deployment host a number of domains using different settings to connect to different databases for each, and thus serving multiple user-facing sites. Hence, multisite.
At first blush, this seems pretty cool, and it is! In the world of clever Drupal hacks, this ranks right up there with imagecache (the trick where we catch 404s for thumbnails that haven't yet been derived and do them just in time). The ability to toggle between different settings based on the domain opens up a lot of interesting use-cases, including rapid site testing and building out "site farms" of many similar sites.
But, as with many clever hacks, there can be hidden costs once they go into production.
